A system includes a coupler with a first arm and a second arm. The first and second arms configured to couple to a roll cage. A first end may include a first recessed portion and a first aperture. A third end may include a second recessed portion and a second aperture. The first and third ends may contact each other and be secured together via a first fastener that passes through the first aperture and the second aperture. Further, the first recessed portion and the second recessed portion may receive a second fastener therebetween that may receive a latch plate of a safety belt or safety harness to maintain it in an upward position.

A wheelchair passenger restraint structure includes: a wheelchair space set in a vehicle cabin so that a passenger of a wheelchair is to be boarded in a forward facing posture; a seatbelt configured to restrain an abdomen part of the passenger of the wheelchair boarded in the wheelchair space; a vertical wall provided behind the wheelchair space in the vehicle-body front-rear direction; and a holding member supported by the vertical wall, the holding member being configured to hold a seating face of the wheelchair from below in the vehicle-body up-down direction.

A vehicle body rear connection structure includes an extension rear transverse that connects a pillar member disposed in a vertical direction of a vehicle body to a transverse member disposed in a width direction of the vehicle body at a rear of the vehicle body, and of which a seat belt mounting portion is formed, and a reinforcement transverse extension which is mounted on a side of the extension rear transverse, and a lower portion of which is connected to a floor panel.

The vehicle body upper structure includes a rear roof rail, a retractor, a webbing, and an anchor. The rear roof rail extends along a roof panel of the vehicle body. The retractor is housed inside the rear roof rail and is fixed to the rear roof rail with a first fastening bolt. For example, the webbing is pulled out in a pull-out direction orthogonal to an axis of the first fastening bolt. A through ring changes a stretching direction of the webbing that restrains an occupant with the webbing to have an acute angle with respect to the pull-out direction.

A method for a seat belt system (10) in a vehicle (14), the seat belt system (10) comprising a control unit (36) and at least one seat belt (18) with an extendable webbing (20) and a webbing extension measuring device (30), includes the steps of: a) determining whether a vehicle seat (16) is occupied, b) determining whether the webbing (20) is in a storage position, if the vehicle seat (16) is not occupied, and c) outputting a warning signal, in particular via an output device (34), if the webbing (20) is not in the storage position.

Moreover, the invention provides a seat belt system (10) for a vehicle (14) comprising an extendable seat belt (17, 18) as well as a vehicle (14) comprising a seat belt system (10).

A restraint system is disclosed for use in vehicle seats that provides enhanced occupant restraint while minimizing belt loading injuries, is intuitive to don and remove, and includes an emergency release feature to allow rapid seat egress by eliminating continuous belt loops. The restraint uses improved belt routing to minimize upper torso rotation, which is critical for vehicles where occupant flail injuries from contact with the vehicle interior are likely. The installed restraint includes a crisscross belt pattern across both the occupant's upper torso and pelvis region, with an alternate configuration which incorporates a single lap belt. The restraint has demonstrated significantly reduced upper torso rotation compared to the current state-of-the-art, 5-point restraint system when exposed to a typical aerospace combined vertical and longitudinal crash pulse yet is as intuitive to don as the typical automotive-style 3-point restraint system.
