An occupant restraint system for a wheelchair user in a vehicle that includes a pivot brace connected to the vehicle structure, a restraint hoop pivotally connected to the pivot brace and adapted to pivot between a stowed position above a wheelchair/occupant receiving area in the vehicle and a deployed position that is forward of a wheelchair/occupant when positioned in the wheelchair/occupant receiving area in the vehicle, and an occupant restraint belt connected to the restraint hoop.

The invention relates to an apparatus for protecting the safety of persons, in particular wheelchair users, in a vehicle, comprising a headrest and/or backrest at least one holder, to which the headrest and/or backrest is attached, for holding the headrest and/or backrest, wherein the holder is adapted to change the horizontal distance (X.sub.K) of the headrest and/or the horizontal distance (X.sub.R) of the backrest in the direction of travel from the person. The invention is characterized in that the holder includes at least one cushioning device for cushioning the impact of a person or a wheelchair against the headrest and/or backrest.

A vehicle includes a vehicle pillar. The vehicle includes a vehicle roof supported by the vehicle pillar. The vehicle includes an airbag supported by the vehicle roof. The airbag has a first side portion, a second side portion spaced cross-vehicle from the first side portion, and a front portion extending from the first side portion to the second side portion. The vehicle includes a pyrotechnic device supported by the vehicle pillar. The pyrotechnic device is coupled to one of the first side portion or the second side portion of the airbag.

A computing device is provided to monitor or ascertain various characteristics of one or more of a wheeled mobility device securement system, a wheeled mobility device, and an occupant of the wheeled mobility device. The computing device can send any and all data available to it, including but not limited to time, dynamic information concerning the vehicle, the wheeled mobility device securement system, the wheeled mobility device, and the occupant, the actions taken by the computing device during an adverse driving condition, and when those actions were taken, to memory for use after the adverse driving event for analysis purposes to understand and recreate the event.

An airbag device includes an airbag that is supplied with gas during a vehicle collision, and that inflates and deploys from a rear side of a vehicle seat toward a front side via an upper side thereof. In an inflated and deployed state the airbag includes a pair of front-rear chambers extending in a front-rear direction via left and right sides of the head of a passenger, and an airbag body in communication with the pair of front-rear chambers, that is disposed at a front side of the passenger between the pair of front-rear chambers, and that is compression deformed in a state supported by the pair of front-rear chambers during restraint of the passenger. The airbag is configured such that entry of at least the head of the passenger into gaps between the front-rear chambers and the airbag body is suppressed during a latter half of restraining the passenger.

An airbag device including an airbag that inflates and deploys from a seat rear side of a vehicle seat toward a seat front side via a seat upper side. In an inflated and deployed state, the airbag includes a pair of front-rear chambers extending in a front-rear direction via left and right sides of a head of a passenger, an airbag body that is in communication with the pair of front-rear chambers and that is disposed at a seat front side of the passenger between the pair of front-rear chambers, and a pair of rear tethers including one-end portions attached to the airbag body and other-end portions attached to a seatback. At a time of restraint of the passenger, the airbag body is pulled by the rear tethers obliquely rearward and downward such that the front-rear chambers press shoulders of the passenger from a seat upper side.

An airbag device includes an airbag that is supplied with gas generated by an inflator during a vehicle collision and that inflates and deploys from a rear side of a vehicle seat toward a front side via an upper side. In an inflated and deployed state, the airbag includes a pair of front-rear chambers extending in a seat front-rear direction via left and right sides of a head of a passenger, an airbag body that is in communication with the pair of front-rear chambers and that is disposed at a front side of the passenger between the pair of front-rear chambers, and a pair of rear tethers including one-end portions attached to the airbag body and other-end portions attached to a seatback of the vehicle seat. At least a rear tether on a side door side is configured so as to be releasable after a collision of the vehicle.

An airbag includes a main inflatable section which includes a front-collision arresting face at the rear plane as deployed, a protruding inflatable section which includes an oblique-collision arresting face, and an arresting recess formed between the front-collision arresting face and oblique-collision arresting face. The airbag internally includes a recess-pulling tether which joints the leading end of the arresting recess and a front end portion of the airbag as deployed, and a regulating tether which extends from the leading end of the arresting recess towards a far-side wall of the protruding inflatable section which is opposed to the oblique-collision arresting face. A joint position of the regulating tether to the far-side wall is such a position that would produce a pulling force which pulls the protruding inflatable section towards the rear plane of the main inflatable section when the leading end of the arresting recess moves forward at catching a passenger.

A child safety seat accident detection system that has a device such as an accelerometer for determining an acceleration of the seat, and a processor, operably connected to the device for determining an acceleration of the seat, and that is configured to judge, based at least on the determined acceleration, if the seat has been in a motor vehicle accident.

A vehicle includes a vehicle roof and a vehicle floor spaced downwardly from the vehicle roof. The vehicle includes a post slidably supported by one of the vehicle floor and the vehicle roof and a tether slidably engaged with the other of the vehicle floor and the vehicle roof. The tether extends from the other of the vehicle floor and the vehicle roof toward the post. The post is slidable relative to the vehicle floor and the vehicle roof from a stowed position to a deployed position. The vehicle includes a support member mounted to the post between the vehicle floor and the vehicle roof. The vehicle includes an airbag supported by the support member. The airbag is inflatable to an inflated position when the post is in the deployed position.
