A reinforced spool assembly has a shaft, a spool member coaxially mounted around the shaft, and two ratchets mounted on two axial ends of a combination of the shaft and the spool member. Each one of two ratchets has a body having an inner surface. The two inner surfaces of the two bodies face each other. In each one of the ratchets, the body has a reinforced supporting structure. The reinforced supporting structure is located between the shaft and the spool member and is offset from the inner surface of the body. A reference plane is defined on and extends along the inner surface of the body, is perpendicular to a central axis of the shaft, and passes through the reinforced supporting structure. Mechanical strength of the reinforced spool assembly is increased by the reinforced supporting structure.

A multi-point seat belt safety apparatus and system and device that automatically moves, adjusts, or otherwise corrects itself around one or more webbing deflection points, and utilizes different components, to accommodate seat occupants with different sizes and ages. In particular, when an occupant extends the webbing across their torso towards an anchor point, generally disposed to the near the side of their waist, the webbing first contacts the torso/shoulder of the occupant at a particular distance above the seat, which is reflective of the occupant's height, causing the webbing to automatically move along a length of a deflection element, positioned at, above, or near the shoulder of the seat occupant, to an appropriate deflection point. At such, the webbing is kept at a proper location, away from the neck of the occupant.

A webbing take-up device is provided with a spool and a stopper member. A webbing is taken up onto the spool. The spool includes a webbing insertion hole into which the webbing is inserted. The stopper member secures an end portion of the webbing at the spool by engaging with a periphery portion of the webbing insertion hole. The webbing take-up device is also provided with load bracing portions (a portion at an axial direction one side of a first serrated portion and a portion at an axial direction another side of a rod portion that are formed at a torsion shaft). The load bracing portions are disposed at the diametric direction inner side of the spool relative to the stopper member and are disposed to be close to the spool. The load bracing portions brace a load that is applied to the spool from the webbing via the stopper member.

The invention relates to a belt reel (10) for a seat belt of a vehicle, said reel comprising a plastic base body (22) with a receiving chamber (26) that contains a belt strap pin (34) for securing a belt strap (36). In said reel, a first end (52) of the belt strap pin (34) is directly supported on the base body (22) of the belt reel (10) and a second end (56) of the belt strap pin (34) is secured in a separate receiving part (54) that is attached to the base body (22).

A reinforcing member (36) for a belt shaft (10) comprises an elongate central portion (46) and two hooking portions (48) provided at the ends of the central portion (46) adapted to be hung into a hooking slit of a belt shaft body (28) of a belt shaft (10), wherein the central portion (46) includes a retaining portion (50) adapted to be encompassed by the webbing (26) and a supporting portion (58) extending in the longitudinal direction (L) substantially over the entire central portion (46) and being offset relative to a plane (M) which is defined by the retaining portion (50), and wherein retaining lands (60) defining a passage window (62) for the webbing (26) extend between the supporting portion (58) and the retaining portion (50). The invention further provides a belt shaft (10) comprising a belt shaft body (28) as well as an end fitting tensioner (12).

The present invention provides a winder used for a force limiting safety belt, comprising: a winder frame, a reel and a torsion bar. wherein, the winder frame comprises two opposite sidewalls, the corresponding positions of the two sidewalls having circular openings provided, the circular openings having internal toothed segments; the reel comprising a spindle through hole provided along the central axis of the spindle, two detachable end covers provided respectively on the two ends of the spindle, the end covers having external teeth provided along the periphery of the end covers; the torsion bar is divided into two segments in axial direction which are connected to each other by adjoining ends; in a free state, the reel is able to rotate and float provided within the winder frame, two end covers being provided in the circular through opening on the two sidewalls of the winder frame.

A belt reel (14) for a belt retractor (10) has a rotational axis (R) and a reel body (16) that is provided as a reel for a webbing (24) and has a first axial circumferential circle (34). The reel body (16) further includes a radial constriction (32) having a second axial circumferential circle (36), wherein the constriction (32) is arranged centrally on the reel body (16) in the axial direction (A) and wherein the circumference of the second axial circumferential circle (36) amounts to a maximum of 95% of the circumference of the first axial circumferential circle (34). Moreover, a belt retractor (10) comprising such belt reel (14) is described.

A belt shaft housing (40) for a belt shaft of a seatbelt system comprises a shaft holder (42) for holding the belt shaft, a securing component (48) including a retaining portion (88), and at least one fixing element (74) that is configured to fasten the belt shaft within the shaft holder (42). The securing component (48) is fastened to the shaft holder (42) such that it can adopt an assembly position and a securing position, wherein the fixing element (74) is released in the assembly position and is secured to the shaft holder (42) in the securing position. Further, a belt shaft including a webbing, a belt pin and a sleeve-shaped axle is provided. There is moreover provided a belt tensioner, especially an end fitting tensioner, comprising such belt shaft housing (40) and such belt shaft as well as a method for assembling such belt tensioner.

The invention relates to an active restraint system (1), comprising a seat belt retractor (3), having a frame (2) and a belt reel (4) with a belt webbing (10) wound thereon and rotatable supported by the frame (2) for allowing winding and unwinding the belt webbing (10). An electric disc motor (28) comprising a rotor (30) and a stator (32) is attached to the belt reel (4). The rotor (30) is directly attached by an attachment (31) to the belt reel (4). The restraint system further comprises a control unit (40) connected to the disc motor (28) and adapted to control the disc motor (28) to drive the belt reel (4) in accordance with a determined belt motion profile.

A three-point installation bracket for converting a two-point seat belt system included factory in a convertible vehicle to a three-point seat belt system without requiring modifications/changes to the existing vehicle frame. The disclosure also includes methods for installing the bracket, as well as kits including same.
