    Background
    [001] To protect workers who have to work at heights, safety lines attached to safety belts worn by a worker are often necessary. If a fall event occurs, the lifeline (attached to a support structure) limits the worker's fall. A worker can be subject to injury even with the use of a lifeline system if a fall distance from which the lifeline is extended is significant. Energy absorbers have been added to lifeline systems to provide a less abrupt stop when the lifeline becomes stretched there, lessening the possibility of injury. An energy absorber works by absorbing some kinetic energy from the falling body (ie, the kinetic energy of the falling worker). Various types of energy absorbers have been implemented in the past, such as spring-type arrangements and deforming metal arrangements. However, these types of mechanisms tend to be bulky and relatively heavy.
    [002] For the reasons set out above and for other reasons set out below, which will become apparent to those skilled in the art after reading and understanding the present specification, there is a need in the art for an effective, efficient and compact energy absorber. Invention Summary

The first strap of straps has a first end part, a second end part and an intermediate section between the first end part and the second end part. The second strap of straps has a first end portion, a second end portion and an intermediate section between the first end portion and the second end portion. A plurality of tear yarns couple the intermediate sections of the first and second belt strips to form an intermediate portion located centrally of the first and second belt strips. The energy absorbing system further includes a first connector and a second connector. The first end part of the first belt strip and the second end part of the second belt strip are coupled to the first connecting element. The first end part of the second belt strip and the second end part of the first belt strip are coupled to the second connecting element such that when the first and second connecting elements are pulled away from each other during a falling event of the tear yarns holding the middle part of the first and second strap strips are generally torn simultaneously from the opposite ends of the middle part of the first and second strips which absorb energy therein until the first and second strips of belt are separated.

    [014] In the following detailed description, reference is made to the accompanying drawings, which form a part thereof, and in which it is shown by way of illustration of the specific embodiments in which the inventions may be practiced. These modalities are described in sufficient detail to enable those skilled in the art to practice the invention, and it is to be understood that other modalities can be used and that changes can be made without departing from the spirit and scope of the present invention. The following detailed description is therefore not to be taken in a limiting sense, and the scope of the present invention is defined only by the claims and their equivalents.
    [015] Embodiments of the present invention provide an energy absorbing system 100 that is efficient and relatively compact. Furthermore, the embodiments of the present invention provide an energy absorber, without the need for an additional back strap, as discussed below. Referring to Figure 1, one embodiment of an energy absorbing system 100 is illustrated. The energy absorbing system 100 includes a first carabiner 102 (first connector) and a second carabiner 104 (second connector). It should be understood that any type of connector can be used and the present invention is not limited to carabiners. Coupled between the carabiners is an energy absorber 200. In use, the energy absorber system 100 is coupled between a safety harness worn by a user and a lanyard by karabiners 102 and 104. The lanyard would then, in turn, be coupled to a support structure. If a fall event has occurred, carabiners 102 and 104 would be pulled away from each other, while energy absorber 200 absorbs energy as described below. The energy absorber 200 includes a first strap strip 110 and a second strap strip 120.
    [016] The first strip of straps 110 and 120 of the second strip of straps are woven together with the tear yarns as shown in figures 3A and 3B. The first strap strip 110 and the second strap strip 120 may be referred to as tear straps. An example of tear yarns used to couple the 110 and 120 strap strips together is 250 polyester tear yarns. An example of a company that manufactures the tear yarns is Sturges Manufacturing, Inc. Company of Utica, New York. First belt strip 110 and second belt strip 120 in embodiments each include a centrally located intermediate section 110c and 120c (illustrated in Figure 3A). Intermediate sections 110c and 120c of the centrally located first and second strap strips 110 and 120 are woven together by tear yarns 250 to form an intermediate portion 130 of the first and second strap strips 110 and 120. The tear yarns 250 couple the first and second straps 110 and 120 together. The first and second straps 110 and 120 have opposite end portions 110a, 110b, 120a and 102b, which are not held together by tear threads 250. In one embodiment the first and second straps 110 and 120 are made to from Vectran. In other embodiments, other types of high strength fibers are used for belt straps 110 and 120, such as, but not limited to, Dyneema, Spectra, etc. Typically, lower strength fibers of a different material are used for the tear yarns 250 such as, but not limited to, polyester fibers. The use of different materials between the strap strips 110 and 120 and the tear wires 250 allows the energy absorbing material to exhibit high strength in a small amount of space. Furthermore, because the fibers in the belt strips 110 and 120 are much stronger than the fibers in the tear strands 250, the fibers in the belt strips 110 and 120 are not damaged as the tear strands 250 are broken.
    [017] Referring back to Figure 1, the respective end parts (first end part of the first belt 110a, second end part of the first belt 110b, first end part of the second belt 120a and the second part of the second strap end 120b) of the first and second strap straps 110 and 120 are strategically coupled to the associated carabiners 102 and 104. In particular, the first end portion 110a of the first strap strap 110 is coupled to the first carabiner 102 Also coupled to the first carabiner 102 is the second end portion 120b of the second strap strip 120. The second end portion 110b of the first strap strip 110 and the first end portion 120a of the second strap strip 120 are attached to the second carabiner 104. As illustrated in Figure 1, the first strap strip 110 in this embodiment includes a twist 111 so that the strips 110 and 102 can be passed a piece. the other. The twist 111, however, is not limited to the first belt strip 110. Therefore, in another embodiment, the second belt strip 120 would include the twist 111. As further illustrated in Figure 1, the intermediate portion 130 of the energy absorber 200 in this embodiment it is a spool configuration to form a spool of woven belts 112. This configuration reduces the overall size of the energy absorber 200 during non-use. In other embodiments, the intermediate portion 130 is folded rather than rolled during non-use.
    [018] Figure 2 also illustrates the energy absorbing system 100. In this figure, the torsion 111 is not illustrated. The first strap strip 110 is shown in Figure 2 as being disconnected at ends 111a and 111b, for illustration purposes only. It should be understood that the ends 111a and 111b of the belt are connected in a twist or bend 111, as shown in Figure 1. As further illustrated, the first end part 110a of the first belt strip 110 and the second end part 120b of the second strap strip 120 are passed through a first connecting opening 103 of the first carabiner 102 and folds further back on itself to form a first part of the connector 215. They are then connected by attaching seam 220 to engage the straps. of strap 110 and 120 to the first carabiner 102. The second end portion 110b of the first strap strip 110 and the first end portion 120a of the second strap strip 120 are passed through a second connecting opening 106 of the second carabiner 104 and folds over itself to form a second part of connector 217. They are then connected, attaching seam 220 that attaches strap strips 110 and 120 to second carabiner 104. As illustrated o in Figure 1, the respective bending portions of the end portions 110a, 120b and 110b and 120a form connector loops 108a and 108b in which the respective connectors 102 and 104 are received.
    [019] The carabiners illustrated in Figure 2 include the respective hook body parts 102a and 104a, blocking the ports 102b and 104b and the connecting parts 102c and 104c. Connecting portions 102c and 104c include respective connecting openings 103 and 106. As discussed above, although carabiners 102 and 104 are shown, it should be understood that any type of connector may be used that can be mated to the connector loops. 108a and 108b of strap straps 110 and 120. In a typical application as discussed above, carabiners 102 and 104 would be used to couple the energy absorbing system 100 between a safety harness worn by a worker and a lanyard attached to a support structure.
    [020] Referring to Figure 3A an illustration of the energy absorber 200 of a mode in an inactivated state is illustrated. In this illustration, the energy absorber 200 is shown not having its intermediate portion 130 on a coil for illustration purposes. Figure 3A further shows the arrangement of the strap strips 110 and 120. In particular, Figure 3A illustrates the positioning of the respective end portions 110a, 120b and 110b, 120a of the strap straps 110 and 120 and the positioning of the located intermediate part centrally 130. As illustrated, the centrally located intermediate portion 130 of the strap strips 110 and 120 are held together by the tear yarns 250. In one embodiment, the intermediate portion 130 of the strap straps 110 and 120 includes first and second sections upward slanted transition sections 225a and 225b which are located near the respective initial areas of the intermediate portion 130. The upward slanted transition sections 225a and 225b provide upward slanted tear strengths so that when a fall event occurs, the portion The intermediate 130 of the strap strips 110 and 120 starts to move away from each other relatively easily, due to a low resistance to scratching. go and then transitions to a desired higher tear strength. This prevents shock from the belts (from strands ranging from no tear (ie no tear resistance)) to the desired tear resistance) from damaging the belt sections 110 and 120. The transition sections 225a and 225b can be achieved by varying one of the tear yarn densities, the tear yarn material used and the tear yarn diameter.
    [021] In the energy absorber 200 embodiment of Figure 3A, the intermediate portion 130 further includes a centrally located loose section 230. In the central loose section 230, the first and second strap strips 110 and 120 are not connected by tear wires. . In one embodiment, the central loose section 230 of the intermediate portion 130 is approximately four centimeters. The center loose section 230 prevents strap strips 110 and 120 from attaching (attaching) over each other. This unintentional attachment of straps 110 and 120 can occur due to twisting 111 (discussed above) in straps 110 as strap straps 110 and 120 become separated. This connection of the strap strips 110 and 120 can damage the overall strength of the strap straps 110 and 120. As discussed above, the strength of the strap straps 110 and 120 needs to be maintained since the strap straps 110 and 120 they double not just as an energy absorber, but as back straps. Thus, the center loose section 230 prevents twisting 111 of connecting the loose straps 110 and 120 together after a fall event has completed.
    [022] The intermediate portion 130 of the 3A embodiment further includes the first and second downwardly sloping transition sections 227a and 227b which respectfully lead into the central loose section 230. The first and second downwardly sloping transition sections 227a and 227b transition from the desired tear strength of the intermediate portion 130 to no tear strength of the central loose section 230. This prevents an instantaneous belt crash on the belt strips 110 and 120 as the belt strips 110 and 120 become separated. This clash of the straps can damage the overall strength of the strap strips 110 and 120. As noted above, the overall strength of the strap straps 110 and 120 must be preserved since the strap straps 110 and 120 are used as the back straps. In one embodiment, the first and second downward sloping transition sections 227a and 227b are approximately 1 inch long.
    [023] Figure 3B illustrates the energy absorber 200 during a fall event. During a drop event the end parts 110a, 120b and 110b, 120a are respectfully separated from each other as illustrated. As the tear wires 250 are separated from each other, they are broken along the separation areas 302a and 302b. Therefore, in this embodiment, the intermediate portion 130 of the straps 110 and 120 is pulled away from each other at two locations 302A and 302b generally simultaneously. Energy absorber 200 continues to absorb energy until intermediate portion 130 of strap strips 110 and 120 are fully separated from each other. This is shown in Figure 3C. As illustrated in Figure 3C, the intermediate portion 130 of the strap strips 110 and 120 is not connected. However, because of the mating configuration, strap strips 120 and 110 remain mated between connector loops 108a and 108b. Thus, a traditional back strap required in a typical energy absorbing system is not required with the embodiments of the present invention. In modes, the configuration will retain the strength necessary for the development of later traction needs. For example, in one modality, the straps provide a tensile strength of 8500 lbs. In addition, the two straps 110 and 120 provide an additional back strap over a typical system to provide a safety feature. Thus, even if one of the strap straps 110 and 120 fails during a fall event, the other strap will still provide the rear strap function which is to retain a connection between a lanyard and a safety harness worn by the worker after the absorber of energy being spent.
    [024] Although specific modalities have been illustrated and described here, it will be appreciated by those skilled in the art that any arrangement, which is calculated to achieve the same effect, can be substituted for the specific modality shown. This application is intended to cover any adaptations or variations of the present invention. Therefore, it is manifestly intended that this invention be limited only by the claims and their equivalents.
