A seat back (35) with a headrest (40) on a vehicle seat (33). To reduce the whiplash effect during a front-end accident to a significant degree, the head rest (40) rests on a headrest support (38) that can be pivoted outward and forward around a horizontal axis (39), with the backward displacement of the support being restricted in terms of movement.

A passenger restraint system for use with a vehicle having a seat includes an inflatable member fixed to the seat and having a guide channel. The passenger restraint system further includes a safety belt system having a torso section extending through the guide channel, wherein the torso section is moveable with respect to the inflatable member.

A seat restraint system whose torso belt includes an inflatable structure that inflates upon impact to protect the occupants of a vehicle such as an automobile. The inflatable structure is linked to a gas generator and crash sensor. When an impact above a predetermined level of severity is detected, the gas generator is ignited, inflating the inflatable structure which contracts in length as it inflates. In a preferred embodiment, the inflatable structure is a braided tube. As the braided tube inflates, the diameter of the tube increases significantly and its length decreases significantly, due to the orientation of the fibers comprising the braided tube. The contraction in length pretensions the seat belt system by pulling any slack out of the seat belt systems. In a frontal impact, the inflated structure restricts the forward motion of an occupant and distributes crash loads over a larger occupant surface area to reduce both primary and secondary injuries. In a side impact, the inflated structure passes over the occupant's shoulder, restricts occupant motion, distributes crash loads and provides head and neck protection.

A seat cushion airbag unit is provided at each seat and includes a seat cushion airbag. The seat cushion airbag is disposed in an inboard portion of a seat cushion of the seat so as to support an inboard portion of buttocks of an occupant in the seat. The seat cushion airbag is changed from its inflated state from its shrunk state when the side crash or rollover of the vehicle is predicted by a controller. Thereby, the occupant's head is moved toward the center of the vehicle. Accordingly, the occupant protection device can promptly move the occupant's head toward the center of the vehicle, preventing the head from hitting against the vehicle roof, at the vehicle side crash or rollover.

An apparatus (40) pretensions seat belt webbing (16) which is extensible about an occupant of a vehicle seat (14). The apparatus (40) includes a movable first member (140), a connector (42) for connecting the first member (140) with the seat belt webbing (16), a movable second member (200), a pyrotechnic device (120) for applying a force to the second member (200) to move the second member, and force limiting coupling device (240). The force limiting coupling device (240) couples the first member (140) and the second member (200). The coupling device (240) moves the first member (140) with the second member (200) until a predetermined force is applied by the connector (42) to the first member (140) resisting movement of the first member with the second member. Thereafter, the coupling device (240) enables the second member to move relative to the first member.

Arrangement and method for determining weight of an occupying item in a seat including one or more weight sensors arranged to obtain a measurement of the force applied to the seat, a forcing function determination arrangement for measuring a forcing function of the seat and a processor coupled to the weight sensor(s) and forcing function determination arrangement for receiving the measurement of the force applied to the weight sensor(s) and the measurement of the forcing function from the forcing function measurement system and determining the weight of the occupying item based thereon. The forcing function determination arrangement may include an accelerometer and measures effects on the seat caused by load of a seatbelt associated with the seat and/or effects on the seat of road roughness, steering maneuvers, and a vehicle suspension system.

A utility vehicle including: a vehicle body frame; a pair of left and right front wheels and at least a pair of left and right rear wheels that are supported on the vehicle frame; a front seat that is provided to the rear of the front wheels; a rear seat that is provided to the rear of the front seat having an in-use position, a transition position, and a non-use position; a cargo bed, disposed to the rear of the front seat including: a bottom wall portion whereon the seat cushion portion of the rear seat is provided movably; a left side wall portion and a right side wall portion that are provided on the left and right side portions of the bottom wall portion, wherein the left side wall portion and the right side wall portion extend forward to the rear seat in its non-use position; and a rear wall portion that is provided at the rear end portion of the bottom wall portion; and a rear floor provided between the front seat and the rear seat and lower than the bottom wall portion of the cargo bed.

A seat restraint system whose torso belt includes an inflatable structure that inflates upon impact to protect the occupants of a vehicle such as an automobile. The torso belt is secured to an anchor arm that is pivotally mounted on a side surface of a seat of the vehicle or a side structure of the vehicle. The anchor arm is rotationally biased to remove slack in the torso belt and locks up in the event of a vehicle crash or sudden stop. The inflatable structure is linked to a gas generator and crash sensor. The gas generator may be mounted in the seat or within the anchor arm itself. When an impact above a predetermined level of severity is detected, the gas generator is ignited, inflating the inflatable structure which contracts in length as it inflates. In a preferred embodiment, the inflatable structure is a braided tube. As the braided tube inflates, the diameter of the tube increases significantly and its length decreases significantly, due to the orientation of the fibers comprising the braided tube. The contraction in length pretensions the seat belt system by pulling any additional slack out of the seat belt systems. In a frontal impact, the inflated structure restricts the forward motion of an occupant and distributes crash loads over a larger occupant surface area to reduce both primary and secondary injuries. In a side impact, the inflated structure passes over the occupant's shoulder, restricts occupant motion, distributes crash loads and provides head and neck protection.

The present invention relates to a roll bar structure of a vehicle equipped with side panels and an open top, comprising a crossbar having a closed section and extending in a vehicle width direction between both of the side panels, roll bars having a reverse-U shape and at least part thereof projecting above the crossbar, and through holes formed at upper and lower portions of the crossbar, wherein an one-side part of roll bar extending substantially vertically penetrates the through holes, and the roll bars are connected respectively with the upper and lower portions of the crossbar which the roll bars penetrate. Accordingly, a resistance of the roll bar structure against a vehicle rollover can be increased by connecting firmly the roll bars with the crossbar.

A vehicle occupant restraint system includes a belt web, a belt retractor, a belt buckle, an insertion tongue, two belt tensioners, one of which is a retractor tensioner and the other a buckle tensioner, as well as at least one control unit coupled to the belt tensioners, this control unit activating the belt tensioners in a restraint situation. Instead of the buckle tensioner a end fitting tensioner can be provided.
