    forged damping movement, as shown by double arrow 7. In addition, seat 1 can move in any other direction between arrows 6 and 7 as shown, for example, by additional double arrows 8 and 9, i.e., the seat can perform damping from the nominal center position in any direction in the horizontal plane in response to vibration and other movements, i
    The seat 1 has three different handles — a longitudinal movement locking lever 10, a rotation locking lever 11, and a damping locking lever 12.
    The seat 1 is mounted on two slide guides. When moving out of the locking lever 10, the seat 1 is disconnected from these slide guides, which allows the longitudinal position of the seat 1 to be adjusted relative to the support 5. When the desired longitudinal position of seat I is reached, the lock lever 10 is released, the stopper seat is position The rotation lock lever 11 can be used to prevent rotation of the seat 1. When the lever 1I is in one position, the seat is free and can rotate or swing relative to the support 5. When lever II is moved to the opposite position, the seat 1 is locked in a given angular position and. cannot rotate. When the damping interlock lever 12 is in one position, seat 1 is free and can perform damping movement in any direction indicated by double arrows (- 9, In the nominal center position of seat 1, arm 12 can be moved to the opposite position to block the damping seat movement,
    The support 5, located under the seat cushion 2, provides both the swing of the seat 1 and the damping movement in any direction (FIGS. 2-12),
    Seat I includes a longitudinal movement device comprising two sliding controls 13 and 14, which are mounted mainly parallel to one another. on the support structure for the seat, for example on support 5 (FIG. 1).

    Regulators 13 and 14 have a S1 bib; the structure and each of them contain an elongated lower fixed guide 15 for fastening the support 5 the upper guide in the form of a hollow casing 16, partially surrounding and sliding along the lateral guide 15, Part of the outer edge of the upper hollow casing 16 of the sliding regulator 13 has a gap In order to show a series of holes 17 spaced apart from each other along the outer edge of the lower guide 15, the locking lever 10 sets the position of the adjusting latch 18 so that two teeth 19 of the latch 18 fit into two holes 17, the stopper the seat 1 is in the desired longitudinal position on the lower guide 15. This secures the base plate 20, which is fixed on the upper hollow casing 16 of the slide adjusters 13 and 14, to be fixed in the desired longitudinal position.
    The base plate 20 and the sliders 13 and 14 jointly form the base part 21 for the seat 1. After adjusting the sliders 13 and 14, the base plate 20 remains fixed on the support 5 using the adjusters 13 and 14 in the desired longitudinal direction. After that, the remaining parts of the seat I can move relative to the base plate 20 to dampen vibrations and other movements that seat 1 can undergo.
    A support plate 22 is mounted on the base plate 20 for supporting the bearings (Fig. 3), which contains an intermediate portion 23 of the seat. Bearing plate support 22 has three different round bores 24 for three different bearing groups 25. Each bearing group 25 (FIGS. 7 and 2) consists of a felt seal 26 inserted into the bore 24, and a plurality of bearing balls 27 located in when the groups of bearings 25 are installed in the holes 24, the balls 27 are in contact with the upper surface of the base plate 20 and the lower surface of the lower support plate 28 located above the support plate 22.
    The bottom support plate 28 includes the lower part of the seat-based assembly 29.

    Bearings 25 allow the support plate 22 to move relative to the base plate 20, and the lower support plate 28 to move relative to the support plate 22. These relative movements are limited to predetermined axes by longitudinal cuts and the rollers included in them. The support plate 22 has the first .pair longitudinal slits 30, located in it in front and behind.
    The slits 30 (FIG. 3) have longitudinal axes 31 parallel to the first axis.
    32, passing through the bearing plate 22 to support the bearings in the longitudinal direction; A pair of first rollers enters the longitudinal slits 30
    33, which are rotatably seated on the upper surface of the base plate 20 with two fingers 34 attached to the plate 20 with locking nuts 35. Each roller 33 is located in its slot 30 with a sliding fit, and the slots 30 can move relative to the roller 33 located in her. This allows the base plate 22 to slide along the base plate 20 in the longitudinal direction shown by a double arrow 36 parallel to the direction of the first axis 32. Balls 27 in bearing groups 25 roll along the upper surface of the base plate 20, making it easier to slide. Thus, the intermediate part 23, consisting of the support plate 22, is capable of moving relative to the part
    2 bases, consisting of a base plate 20 and sliding regulators 13 and 14, along the first axis 32, Support plate 22 also has a second pair of slots 37 located on opposite sides of the support plate 22, Slots 37 have longitudinal axes 38, which lie along the second axis 39. The second axis is perpendicular to the first axis 32 and extends in the lateral direction of the seat I. A pair of second rollers 40, planted with the possibility of sliding below the bottom support plate 28 using two pins 41 attached to the support plate 28 retaining nuts 42, enters into oppositely arranged slits 37, whereby the lower support plate 28 can make a sliding movement relative to the support

    plates 22 in opposite directions along the second axis 39, as indicated by the double arrow 43,
    The balls 27 of the various groups of bearings 25 are in contact with the lower surface of the lower support plate 28, facilitating the relative sliding movement. The rollers 40 move along the slots 37, being in them on a sliding fit, which ensures the linearity of the relative movement along the second axis 39. Thus, the seat-based assembly 29 which ends in the lower support plate 28 in its lower part can perform a linear movement. relative to the bearing retainer plate 22 comprising an intermediate portion 23.
    The sleeve 44 is installed in the center of the base plate 20 by means of a spring washer 45 and a lock nut 46, the sleeve 44 extends upwardly mainly in the vertical direction from the base plate 20 through the elongated hole 47 in the lower support plate 28 of the retaining tongs, the sleeve 44 has a rubber insert 48 over base plate 20. The holes 47 and 49 are appropriately sized and shaped to allow sufficient movement of damping between the base plate 20, the bearing support plate 22 and the lower support plate 28. Part of the outer edge of the lower support plate 28 has many teeth 50 that are used for locking seat rotation
    The seat pad 2 (FIG. 1) is mounted on the seat mounting plate 51 along with the backrest 3 and the armrests 4. The seat rotates so that the seat mounting plate 51 can rotate relative to the lower support plate 28. This is partially achieved by the rotation disk 52 mounted on the bottom support plate 28 and made of plastic or other low friction material to facilitate sliding of the seat mounting plate 51 over it. At the same time, the PTGit 51 of the seat, the rotational disk 52 and the lower support plate 28 are held in a concentric position by means of a clamp 53 with an upper end 54, the clamp 53 is mounted in a circular central hole 49 in

    lower support plate 28 and passes through a central round hole. 55 slightly larger in rotation disk 52 and through a slightly larger central hole 56 in the seat mounting plate 51. The upper end 54 of the collar 53 terminates in a central circular hole 57 in the lower support disk 58 located on the seat mounting plate 51. If the damping movement of the seat-based assembly 29 is large enough, the collar 53 blows into the rubber insert 48 mounted on the sleeve 44,
    In order to hold together the seat base 29, the intermediate part 23 and the base assembly, it is necessary to limit the upward movement of the seat mounting plate 51 relative to the base plate 20. This is done by an upper supporting disk 59 and a supporting plate 60 mounted on the upper end of the sleeve 44 and fixed to it with a spring washer 6J by a nut 62 with longitudinal slits and a pin 63, the supporting plate 60 also has a central hole 64 large enough for mounting sleeves 44, the support plate 60 has a plurality of bearing balls 65 mounted for rotation around the outer periphery thereof, in contact with the underside of the upper support disk 59, and with the upper surface of the lower support disk 58,
    When the bearing plate 22 is made to hold the bearings and the lower base plate movement relative to each other and against the base plate 20, the yoke 53 is pulled out from the concentric state with the sleeve 44, moving it during such movement. The rotation disk 52, the mounting plate 51 and the lower disk. The disk 58, which rotate on the yoke 53, make a similar movement with respect to the sleeve 44, while the upper bearing disk 59 remains concentrically located at the top end of the sleeve 44. This relative movement is allowed balls 65, which roll over the upper surface of the lower support disk 58, when the lower support disk 58 moves relative to the support plate 60 and the upper support disk 59,
    The seat 1 is typically held in its nominal center position by positioning the mounting plate 51 so that the sleeve 44 is in the center of the circular hole 56 in the mounting plate 51. This is accomplished by the sin of various springs 66 - 68 located at equal distances around sleeve 44 and stretched between sleeve 44 and various parts of the seat mounting plate 51. The springs 66 - 68 are attached to the bushing with the help of a cross piece 69 having three cross fingers 70 protruding from it. Each finger 70 ends with a roller 71 on which one end of the corresponding spring 66 - 68 is wound. The other end of the spring-66 is attached to ) the seat mounting plate 51 on the inner loop 72 at the right angle to the right edge of the mounting plate 51. The opposite end of the spring 67 is attached to the seat mounting plate 51 through a large raised loop 73 at the left rear corner of the seat mounting plate 51. The opposite end of the spring 68 is attached to a raised portion 74 extending across the front end of the seat mounting plate 51.
    In the absence of forces acting on seat 1, springs 66 to 68 hold sleeve 44 in the center of the circular hole 56 to hold the seat in its nominal center position. When forces are applied to seat 1, causing relative movement between the lower support plate 28, the bearing support plate 22 - and the base plate 20, the springs 66 - 68 allow movement, while at the same time providing sufficient resistance to this movement,
    The damping of the movement of the seat 1 and the seat mounting plate 51 relative to the base plate 20 and the sleeve 44 is provided by two shock absorbers. A longitudinal shock absorber 75 is fastened with one end on top of hub 44, and the opposite end on pin 76, located vertically on a raised section 74 in front of the seat mounting plate 51. The shock absorber 75 longitudinal shock is located in a direction parallel to the direction of the per

    plate 22 to hold the bearings relative to the base plate 22. The second (side) shock absorber 77 is located generally perpendicularly to the longitudinal shock absorber 75, at one end is connected with the cross piece 6-9, and at the opposite end is fixed to the pin 78, which is located vertically on the raised eyelet 79 on the left side of the mounting plate 51 seat A side shock absorber 77 dampens the movement of the bottom .plate 28 and the seat mounting plate 51 relative to the bearing support plate 22.
    A design incorporating a lever for locking the longitudinal movement 10 and a mounting latch 18 for adjusting the longitudinal position of the base plate 20 on the slide regulators 13 and 14 is shown in FIG. 9 and 10, as well as in FIG. 2. The mounting latch 18 is pivotally seated from the bottom. base plate 20 near slide regulator 13 with bolt 80, gasket 81 and nut 82, bolt 80 passes down through hole 83 in base plate 20 and through hole 84 at the end of latch 18, where it includes gasket 81 and nut 82 Latch 18 rotates normally. the bolt 80 into the position in which its tooth 19 enters several openings 7 under the action of a latch spring 85. One end of the spring 85 is connected to one end of the latch 18 opposite to the hole 84, and the opposite end of the spring 85 of the latch is connected to the base plate 20 near the sliding regulator 13. With this arrangement, the mounting latch 18 of the base plate 20 and the hollow casing 16 of the sliding the regulator 13 is locked with respect to the lower guide 1 5,
    The adjustment of the longitudinal position of the base plate 20 requires that the latch 18 of the adjuster rotates outward from the slide adjuster 13, the tooth 19 of the opening is out of the holes 17, This is done by manually operating the lock lever 10. The latter is pivotally mounted on the bottom edge of the support plate 22 to hold the bearings with a bolt 86, which passes through the hole 87 on the edge of the support plate 22 and through the hole 88 in
    the end of the locking lever 10 where the lock washer and the hex nut 90 enter. It allows the lever 10 to pivot on the large 86 in response to manual movement of the hinge at the opposite end of the lever 10 from the hole 88, Loop 91 passes below the seat 1 ( fig, 1) making it easier,
    The lever 10 has a downwardly directed flange 92 on one side thereof, which is lowered to the upwardly directed flange 93 on the side of the latch 18 and engages with it. Accordingly, the rotation of the lever 10 is directed away from the slider 13 by manual control of the loop 91, causing The flange 92 pulls the flange 93 and thereby rotates the latch 18 from the slide regulator 13, pulling the tooth 19 out of the holes 17. When you release the loop 9, the latch 18 rotates under the action of the spring 85, having the tooth 19 in the selected holes 17. This action involving b, turning the lever back to a locked or disconnected position is facilitated by a spring 94 of the lever, one end of which is connected to the loop 95 at the end of the latch 18 near the hole 84, and the opposite end to the loop 96 in the central region of the lever 10. holding the bearings on which the lever 10 is attached, is capable of making longitudinal movement relative to the base plate 20. On which the latch 18j is attached, the lever 10 and the latch 18 can be moved. When this happens, the flange 92 slides along the flange 93, and the lever spring 94 bends, as far as necessary, while at the same time keeping the lever 10 in the retracted or locked position. The flange 92 on the fish jare 10 is longer than the flange 93 of the latch 18, which ensures engagement between them regardless of the longitudinal position of the support plate 22 for holding the bearings and the lever 10.
    The design that includes the seat rotation locking lever 1I j is shown in FIG. 2,4,8 and P, the rotation locking tag 11 has an opening 97 at one end and an eye 98 for manual control at the opposite end. One side of the lever I1 contains a downwardly directed flange 99, made with a hole 100, the eyelet 98 protrudes under the seat 1 so that it has manual access,
    The rotation locking lever 11 is articulated with the lower side of the raised portion 74 on the front side of the seat mounting plate 51. This is accomplished by using a bolt 101 directed upward through the bushing and hole 97 in lever 11 and through hole 102 in the raised portion .74, where the bolt 101 is fitted with spring washer 103 and hexagon nut 104, Spring 105 with one end fixed in hole 100 in the flange 99 of the lever 11, and the opposite end is connected with the rear part of the raised portion 74,
    The lever 1 and the spring 105 (FIG. 4) are arranged in such a way that the spring 105 holds the lever 11 in one and opposite positions. When the lever 11 is rotated in a counterclockwise direction (FIG. 4, manually behind the ear 98, the spring 105 contracts and holds the lever 11 in this position. The flange 99 of the lever 11 in this position is located at a distance from the teeth 50 on the outer edge of the lower support plate 28 and the seat can rotate. When the lever 11 is rotated counterclockwise (FIG. 4, the spring 103 is first stretched as the lever moves through the intermediate position, and then compressed when the lever reaches the opposite position, keeping it in this position, B In a false position, the lower edge of the flange 99 of the lever 11 engages with one of the teeth 50 in the lower support plate 28, blocking the rotation of the seat. The tooth 50 passes along part of the outer periphery of the lower support plate 28, making it possible to stop the seat 1 at various desired angular positions .
    A design that includes a damping interlock lever 12 for stopping the seat 1 is shown in FIGS. 2, 4, 5, 8, and 12. A fish 12 that has an eyelet 106 for manual control at one end, is bent upward at the opposite end and ends with a part having an opening 107 The eyelet 106 protrudes from under the seat 1, giving the opportunity

    manual access to it (fig-, i i. gear 12 is hinged to the underside of the raised portion 74 on the seat mounting plate 51 using a bolt 108 that passes through the sleeve 109, the hole 107 in the lever 12 and through the hole 107 in a raised area 74, where a spring nut 110 and hex nut 111 are put on it. The lever 12 has a notch 11 (FIG. 12} in the middle part, which can include and engage the tooth 113 on the damping blocking plate 114, which is hinged to the underside of the raised portion 74 of the mounting plate 51, lifted The first section 74 has two eyelets 115 and 116 on the leading edge that are located at a distance from each other. The ears 115 and 116 have holes 117 and 118, respectively. On the locking plate 114 there are two oppositely located ears 119 and 120 that are hooked respectively, behind the lugs 11 and 116 of the raised portion 74. The lugs 119 and 120 have holes 121 and 122, respectively. Through the hole 121 in the eyelet 119 and the hole 117 in the eyelet 1 15. the pin 123 passes with the linch pin 124. Through the hole 122 in the eyelet 120 and the hole 118 in the ear 116 passes the pin 125 with the cotter pin 126,
    The locking plate 114 is rotated on the pins 123 and 125 so that the curved edge 127 on the rear strut is raised and lowered in response to the swing of the plate 114. The swing of the locking plate 114 is caused by turning the damping blocking lever 12. When the lever 12 is turned against the action of the spring 128, tensioned between the hole 129 in the lever 12 and the hole 130 in the ear 120 of the locking plate 119 and the pull lever 12 into one of the opposite positions, the notch P2 and the lever 12 interlock with the tooth 113 and the cam the action rotates the locking plate 114, raising and lowering its curved edge 127,




    The vertically located pin 131 is slidably mounted using a pin guide 132 mounted on the lower side of the lower support plate 28, and a lock washer 133 and a lock nut 134 located on the opposite side.

    on the side of the bottom onopftciH or on 28. Pin 131 PASSES the skull hole 135 in the plate 28 and can go up and down along the guide 132. The roller 136 is mounted on the upper end of the pin 131 and held by the retaining ring 137. The roller has a groove 138 on the outer periphery, which enters the curved edge 127 of the retaining plate P4 when the seat 1 is facing forward, with the result that the edge 127 is located in the groove 138.
    When the seat 1 is in its nominal center position, the damping movement can be stopped by turning the damping locking lever 12, which turns the locking plate 114 down. The resulting downward movement of the curved edge 127 on the back side of the plate 114 pushes the roller 136 and with it the pin 131 down. When the pin 131 moves downward, it opens a hole 139 at the front end of the base plate 20. In this position of the pin 131, the seat-based assembly 29 is locked by means of an intermediate part 23 on the base part 21, as a result of which there is no weakening movement. The loosening movement can be restored to the seat 1 by rotating the lever 12, as a result of which the stopper plate 114 is turned upwards, the roller 136 rises and with it the pin 131. When the pin 131 is lifted from the hole 139 in the base plate 20, the support plate 22 to hold the bearings and the lower support plate 28 are able to move relative to the base plate 20.
    Alternatively, the seat 140 with a multi-directional vibration damper (FIG. 13) includes a base plate 141 comprising a mounting part 21, a roller assembly 142 containing
    an intermediate portion 23, and a seat support plate 143 comprising a portion of the base assembly 29. The remainder of the base assembly 29, which includes a seat cushion 2, a backrest 3, armrests 4 and a seat rotation mechanism, is not shown in FIG. 13. Any known rotation mechanism can be used.

    The base plate 14 is mounted on the slide regulators 13 and 14, Two opposite; the edges of the base plate 141 extend upward to form the guides 144 and 145, into which the opposite edges 146 and 147 are inserted, respectively, of the roller assembly 142. Roller assembly 142 comprises a first group of rollers in the form of four different rollers 148-151 mounted rotatably within assembly 142 about a group of first parallel axes, which includes an axis 152 on which rollers 148 and 149 rotate. Rollers 148-151 pass t under the bottom surface of the roller assembly 142 and are in contact with the top surface of the base plate 141. Therefore, the roller assembly 142 may laterally move relative to the base plate 141 in opposite directions along the transverse axis, as indicated by the double arrow 153.
    The movement of the roller assembly 142 in the directions depicted by the arrow 153 is limited to two springs 54 and 155. One end of each spring 54 and 155 is connected to a stud 156, which is attached to the base plate 141. The opposite ends of the springs 154 and 155 are connected to the opposite parts 157 and 158, respectively, of the roller assembly 142. The springs 154 and 155 lie on a common longitudinal axis that is parallel to the arrow 15.3. Moving the roller assembly 142 in the directions of the arrow 153 is damped by the first shock absorber 159, located parallel to the springs 154 and 155, One end of the shock absorber 159 is connected to a stud 160 at the node 142 rollers, and the opposite end with a stud 161, which is mounted on the base plate 141.
    Roller assembly 142 also has a second group of rollers 162-165 rotating about a group of second parallel axes, which includes
