Description

SUSPENSION SEAT WITH ADJUSTING SUSPENSION

Technical field

The present invention relates to a suspension seat harness comprising:

- seating harness consisting of a lanyard and a pair of thigh loops attached to the lanyard by means of lashing straps

- a pair of shoulder straps attached to the front and rear of the securing belt, each of the shoulder straps comprising a chest strap adjoining the dorsal strap forming a half-loop surrounding the user's shoulder,

- and an adjusting hinge consisting of an additional extension strap.

BACKGROUND OF THE INVENTION

Known seat harnesses usually have two attachment points for attaching to the safety rope by means of a fastening hinge and a braking hinge. A first method of hanging at the front abdominal or chest attachment point is shown in Figs. 1 and 2. The brake hinge 50 is attached to the front anchor point with the disadvantage of the presence of the rope 52 in front of the user, which impedes its operation and operation (Fig. 1). On the other hand, in the event of a fall, the user is securely secured by the rope 52 with optimum comfort and the rope 52 is easily accessible, allowing the user to pull back up.

3 and 4, the brake hinge 50 is attached to the rear attachment point with the advantage that the rope 52 is at the rear without interfering with the user's progress or work (FIG. 3), However, in the event of a fall, the user is in an uncomfortable position caught by the rope 52 located in the unreachable position behind him (FIG. 4). Any attempt by the user to correct his position on the rope is impossible in this case.

SUMMARY OF THE INVENTION

SUMMARY OF THE INVENTION The object of the present invention is to provide a reliable suspension seat harness which combines all the advantages of the known solutions in overcoming their disadvantages, i. the user is not restricted by the rope in normal use and is stopped in the event of a fall while maintaining optimum comfort, while maintaining the reachability of the rope in order to allow separate recovery.

The suspension harness of the present invention is characterized in that the adjusting hinge is provided with a first fastening end securely attached to the front of the harness and a second fastening end located at the rear of the harness, wherein said adjusting hinge is positioned on one of the shoulder straps by a removable fastening be in the locked position or unlocked position, depending on whether the pulling force on the adjusting hinge is lower or higher than the set threshold, moving from the locked position to the unlocked position as a result of falling or manually detaching the other end of the shoulder strap; by moving the adjusting hinge forward.

According to a preferred embodiment of the invention, the fastening part of the adjusting hinge is in a locked position on the back strap of the shoulder strap. The first adjusting hinge end of the adjusting hinge is located on a common portion for mounting the chest straps of the two shoulder straps of the securing strap.

The removable fastening portion may comprise at least one strip of a self-adhesive securing tape, a locking system with snap buttons, or elastic securing means.

The suspension seat harness 10 is further provided with an adjusting hanger 40 comprising an additional extension strap having a first attachment end 42 attached to the front of the suspension seat harness 10 and a second attachment end 44 located at the rear of the suspension seat harness 10. The adjustment hanger 40 is positioned. on one of the shoulder straps 14 and the other fastening end 44 is connected to the dorsal strap 34 by means of a fastening portion 46 °

The second mounting end 44 is designed in the form of a circle for connection to the brake hinge via a carabiner. The fastening portion 46 is in the locked position when the brake hinge slides normally along the suspended rope. The force applied to the adjusting hinge 40 during the normal procedure is not sufficient to disconnect the fastening portion 46. The fastening portion 46 is disconnected when the user falls, because the pulling force applied to the adjusting hanger 40 exceeds a set threshold. In this case, the fastening portion 46 ruptures as a fuse and disconnects the user remaining hanging on the rope at the first front fastening end 42 attached to the front of the suspension seat harness 10.

The removable fastening portion 46 may be formed in a variety of ways, for example by means of a web of self-adhesive securing tape under the trade name Velcro (registered trademark), a locking system with patent buttons, or elastic securing means. The fastening portion 46 is preferably located at the beginning of the dorsal strap 34 near the back of the user's arm.

The operation of the suspension seat harness 10 provided with the adjusting hanger 40 according to the present invention is shown in Figures 7 to 9.

In Fig. 7, the fastening portion 46 of the adjusting hinge 40 is shown in a locked position with the back strap 34 and the second fastening end 44 is located with the brake hinge 50 behind the user's back. Rope 52 is still behind the user and does not interfere with normal use in his procedure.

In Figure 8, the fastening portion 46 is unlocked due to a fall and the brake hinge 50 automatically stops the user's movement in the direction

down the rope 52, which is also moving. in front of him. The user is then conveniently connected to the rope 52 by means of the first fixing end 42 of the adjusting hinge 40.

In Fig. 9, the rope 52 is readily accessible and the user can move up or down along the rope 52, which is available for conventional motion patterns.

The fastening portion 46 can be easily detached manually to allow easy adjustment of the brake hinge 50.
