The invention relates to a belt rectractor (10) for a seatbelt of a motor vehicle. The belt retractor (10) comprises a belt spool (14) which is rotationally connected to a belt spool-side end of a torsioning rod, said torsioning rod being operatively connected to a locking mechanism (20) at a locking mechanism-side end. In a locked state, the locking mechanism-side end of the torsioning rod is rotationally fixed to a frame (12). The belt spool-side end can then be rotated relative to the locking mechanism-side end in an unwinding direction (16) under the effect of torsion from the torsioning rod. The belt spool (14) is additionally rotationally fixed to the frame (12) in the unwinding direction (16) in a stopped state of a stopping mechanism (22). The stopped state is set of the belt spool-side end is rotated by a specified number of rotations relative to the locking mechanism-side end in the locked state of the locking mechanism (20). The stopping mechanism (22) comprises a locking pawl which is mounted on the belt spool (14).

A seatbelt pretensioning retractor assembly for use in a passenger vehicle is provided. The pretensioning assembly includes a tube in fluid communication with a gas generator and a driving element disposed therein that travels in a first direction in response to actuation of the gas generator. The driving element includes a plastically deformable polymer rod with a recessed portion. A stopper is coupled to an end portion of the plastically deformable polymer rod. A seal member is disposed between the gas generator and the stopper. The tube includes a projection extending within the tube adjacent to the exit to define a constriction portion. The constriction portion is sized to permit the recessed portion of the plastically deformable polymer rod to pass therethrough while preventing the stopper from passing therethrough.

Provided are a seat belt retractor and a seat belt device with which it is possible to improve an occupant-restraining property and energy absorption characteristics. A seat belt retractor 1 including a spool 2 that winds up a webbing W for restraining an occupant, a shaft 3 inserted through an axial center of the spool 2, and a locking base 4 connected to the shaft 3 and capable of switching between a rotating state and a non-rotating state, further includes an energy absorption device 5 capable of changing an energy absorption amount according to a relative rotation speed between the spool 2 and the shaft 3, and a load adjustment member 6 that blocks or reduces load transmission when a load equal to or greater than a threshold is applied to the shaft 3 or the spool 2. The spool 2, the shaft 3, the locking base 4, the energy absorption device 5, and the load adjustment member 6 are serially connected.

An inertia sensor (10), in particular provided on a belt retractor (12), includes at least two components which are reversibly movable relative to each other and each of which includes at least one contact surface (20, 22, 34, 36) on which the components are in contact with each other, wherein at least one of the contact surfaces (20, 22, 34, 36) is coated with graphite powder (38).

A modular monocoque backrest is provided. The modular monocoque backrest may comprise a front shroud, a back shroud, and an at least one back spar. The front shroud may be coupled to the back shroud, and the back spar may be configured as a mounting point, enabling the modular monocoque backrest to mount to an aircraft floor. The front shroud and the back shroud may comprise a carbon fiber composite material, allowing the modular monocoque backrest to be modular in nature. The carbon fiber composite material may enable the modular monocoque backrest to have a lightweight design while also maintaining resistance to dynamic crash loads.
