A seat belt apparatus includes a main belt, a first buckle that is disposed on an extended part of the main belt and that can be buckled and fastened to a second side of the vehicle seat corresponding to a waist on the other side of the passenger, and an auxiliary belt extending from a second part of a backrest of the vehicle seat corresponding to an underarm of the passenger, where the second part is lower than the first part. The apparatus is configured such that in the event a body of the passenger slides forward relative to the vehicle seat, the underarm of the passenger is blocked by the auxiliary belt.

A web tightening apparatus is disclosed for a multi-point restraint harness having a web extendable about an occupant of a motor vehicle seat. A base frame is mounted between the seat and a floor of a motor vehicle, a web turning guide is mounted to and within the base frame with the web extending into the base frame and through the web turning guide, a ratcheting device is mounted to the base frame and has a handle, and a ratcheting web is coupled at one end to the web extending from the web turning guide and coupled at an opposite end to the ratcheting device. The ratcheting device is responsive to ratcheting actuation of the handle to draw the ratcheting web therein, wherein movement of the ratcheting web into the ratcheting device draws the web further into the base frame and thereby tightens the web about the occupant.

A four-point seat belt device includes two shoulder belts to press the shoulders of a passenger sitting in a seat, a restraint element extending between the two shoulder belts, and a driving unit arrangement to perform winding of the belts upon detection of a collision.

Disclosed is a method of use of a movable seat for a law enforcement vehicle. A method of restraining a detainee within a vehicle may include the steps of: opening a door on a vehicle comprising a movable seat; retracting the movable seat from a first position in the vehicle to a second position adjacent the door of the vehicle; seating a detainee in the movable seat of the vehicle; wherein the detainee's hands are restrained behind its back; positioning the detainee's hands in an opening in a back of the movable seat; restraining the detainee in the movable seat with a seat belt coupled to the movable seat; returning the movable seat to the first position inside the vehicle; and closing the door on the vehicle.

A safety belt structure of racing cars that can be quickly put on and taken off is disclosed. The safety belt structure includes a buckle socket, a buckle clip, and two elastic buckle locks. One end of the buckle socket and the buckle clip are mutually buckled and have a socket part and a clip part. The other ends of the buckle socket and the buckle clip both have a strap-through part and are respectively pivoted with a transverse safety belt. The buckle socket and the buckle clip both have a quick-release buckle clip protruding on one side. One end of the elastic buckle lock has a slot formed to allow the quick-release buckle clip to be inserted into, and the elastic buckle lock can be quickly released by pressing. The other ends of the two elastic buckle locks are formed with a long slot for installing a shoulder safety belt. Accordingly, the two elastic buckle locks can be used to achieve the effect of quickly putting on and taking off the shoulder safety belts.

The patron restraint system for amusement rides includes a locking receiver with a locking assembly for engaging a restraining strap. The engagement of the restraining strap in the locking receiver can be verified by a ride operator by visual or physical inspection, or by a sensor system indicating the locked or unlocked state of the locking receiver. A latching ratchet mechanism may be provided in the receiver to restrict movement of the restraining strap until it is released by the ride operator. The sensor system includes an acoustic sensor that detects alignment of an aperture with a piezoelectric acoustic emitter and an acoustic detector.

Systems for retraining an occupant within a vehicle seat as disclosed herein include a lap belt having connectable lap-belt segments along a seat bottom extending from respective connection points with the seat or the vehicle. A connection element extends upwardly along a seat back from an attachment point to a connecting member, and shoulder straps extend from the connecting member for placement over the occupant's shoulders when seated within the vehicle seat. The lap-belt segments may be connected directly or indirectly with the shoulder straps, and shoulder strap length may be adjusted via the lap-belt segments or an intermediate element used to connect the lap-belt segments with the shoulder straps. A vertical belt extends from the connecting member along the back portion of the vehicle seat to an attachment point within the vehicle.

A vehicular seat belt assembly can include a pair of lateral webbing strips configured to extend laterally across a first portion of vehicular passenger, distal ends being statically secured to the vehicular support structure, and proximal ends being selectively connected to and disconnected from each other. A pair of upper body strips can be configured to contact a second portion the passenger. An anchor can be statically secured to the vehicular support structure, and configured to guide each of the upper body strips so as to enable a change in a direction of extension of the upper body strips, and to thereby absorb a portion of a load created by the force applied to the passenger and applied to the upper body strips. A retractor assembly can be configured to enable length adjustment of the upper body strips if the load is below a certain threshold level.

Web connectors for use in occupant restraint systems in a vehicle are disclosed herein. In one embodiment, first and second web connectors include first and second web receiving portions, respectively. The first web receiving portion includes a first projection at a first side and a first recess adjacent a second side opposite the first side. The first recess includes a first surface feature. The second web receiving portion includes a second recess and a second projection having a second surface feature. In this embodiment, the second recess is configured to receive the first projection, the first recess is configured to receive the second projection, and the first surface feature is configured to engage the second surface feature to resist movement between the first and second connectors during use.

In a four-point seatbelt device including a three-point seatbelt and an automatic belt, the automatic belt is actuated to dispose an anchor at a standby position after the three-point seatbelt has been placed over an occupant. During this operation, the anchor is disposed further to a rear side than a field of vision of the occupant facing toward a front side, for example, and a second webbing is placed in standby in an unrestrained state with respect to the occupant. Moreover, in a case in which a vehicle collision has been predicted by a PCS control section, the automatic belt is actuated to place the second webbing over the occupant automatically.
