A driver seat for an operator includes: a fastener configured to fasten a pair of hip belts; a pair of shoulder belts each having a distal end attached to each of the pair of hip belts, the pair of shoulder belts being configured to hold a shoulder area of the operator; and a fastened-state detector configured to detect whether or not the fastener is fastened. The fastened-state detector includes: a detector main body configured to detect whether or not the fastener is fastened through electrical continuity; a signal line connected to the detector main body; and a bag-shaped section integrated with one of the pair of shoulder belts in a drawing direction of the shoulder belt, the bag-shaped section housing the signal line.

A safety belt automatic adjustment apparatus includes a safety belt buckle fastening assembly, a safety belt retractor and a linking component. The safety belt buckle fastening assembly is rotatably connected to a seat body of a child safety seat and for connecting with a safety belt buckle. The safety belt retractor is used for retracting a safety belt, and the safety belt retractor includes a restraining assembly for restraining a movement of the safety belt in a predetermined direction. The linking component is installed between the safety belt buckle fastening assembly and the safety belt retractor, and the safety belt buckle fastening assembly rotates to drive the linking component and the restraining assembly, so as to restrain or release the safety belt winding around the safety belt retractor. The safety belt automatic adjustment apparatus has advantages of automatic adjustment for the safety belt, simple structure, convenient operation and enhanced safety.

A seat belt retractor that has a simple structure, easy to manufacture and operates accurately is provided, and a seat belt apparatus provided with the seat belt retractor is also provided. The seat belt retractor includes energy absorbing mechanisms that absorb and alleviate the energy of a vehicle occupant by limiting a load applied to a seat belt. The energy absorbing mechanisms is coaxially incorporated in a spool, whose one end portion is retained by the spool and the other end can be locked by the lock mechanism, and obtains a rotational force when being twisted. The second energy absorbing mechanism includes a first rotating member rotatable together with the spool, an abutting member relatively rotatable with respect to the first rotating member by a predetermined angle, a second rotating member relatively rotatable with respect to the abutting member, and an energy absorbing member whose one end portion is fixed to and supported by the second rotating member and the other end portion abuts against the abutting member.

A safety belt retractor, comprising a frame (8) and a belt retracting cylinder (1), the retracting cylinder (1) being rotatably supported in the frame (8) and being composed to be used for winding a woven belt (2). The frame (8) comprises: a back plate (8h), which has a first side and a second side which are opposite to each other, and a first opening (20); a plurality of first supporting legs (8a,8b), extending from the first side of the back plate (8h); a first support plate (11), which is provided with a second opening (21) and is connected to free end regions of the first supporting legs (8a, 8b); a plurality of second supporting legs (8c, 8d, 8e, 8f), extending from the second side of the back plate (8h); and a second supporting plate (9), connected to the free end regions of the second supporting legs (8c, 8d, 8e, 8f). The first opening (20) and the second opening (21) receive the belt retracting cylinder (1). The safety belt retractor is simple in structure and easy to assembly. Also provided is a safety belt device comprising the safety belt retractor.

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.
