摘要:
A restraint device for controlling the head of a driver during a high-performance vehicle collision. The device includes a rigid member positioned along the back of the driver, a tether for attaching the member to the driver's helmet, and a strap for anchoring the device. The vehicle's seat belt assembly or the driver's own body, such as his torso, waist or legs, may be used to anchor the device. During a vehicle collision, forces from the head are transferred through the device (i.e. tether, rigid member, and strap) into the anchor in order to resist forward movement and downward rotation of the driver's head.

Conventionally, head and neck injuries are avoided in rear-end car collisions by fitting airbags of various types, despite the many disadvantages of airbags. The head single-point safety belt system and the head two-point safety belt system avoid the disadvantages of conventional head restraint systems. The invention comprises a head safety belt (7, 14) with a solid reinforcement (5) on the face half running round to the ears. On this solid face half a solid chin hoop (4) with adjustable length (10) is fixed by means of a multistage joint (15). From the back of the head a single belt (27) in the case of a single-point system runs to the headrest (8), where said belt runs via a deflection mechanism (29) to the guide slot of the body three-point safety belt (19) or to a separate slot (18) and is accommodated on a belt take-up roller (22). The invention is characterised in that the blocking of the head safety belt and the body safety belt occurs at one and the same moment by the same blocking mechanism for the belt take-up roller. In the two-point system the head belts (31) for the left and right head halves run separately backwards to two deflector rollers in the headrest (8) and come together in one belt at a suitable distance before the belt take-up roller.

A safety device for a vehicle fitted with a seat belt having at least a lap portion which, in use, extends across the user's upper legs has two spaced apart guides (22) through each of which the lap portion of the belt extends, the guides (22) being located on respective sides of the user's upper legs. In one embodiment, the safety device includes a pad or cushion (10) which, in use, is placed on the vehicle's seat and upon which the user sits. The guides (22) may be anchored to respective sides of the vehicle seat, or the pad or cushion (10), and consist of a sheet of fabric folded in half which is releasably closeable along its free edges by a fastening such as VELCRO (Registered Trade Mark).

A head and neck support and protection device comprising: an arm (1), pivotably mounted to a support (7), comprising a helmet clip (3), at its end opposite to the pivotable mount, configured to engage a helmet pin (22); a resistance block (4, 71, 281) configured to transfer energy into a chassis when the arm (1) hits the resistance block (4, 71, 281); wherein the arm (1) has a slidably-mounted element (2) for connecting it to the helmet clip (3); whereas the slidably-mounted element (2) is configured to slide out of the arm (1), in a controlled manner, when conditions indicating a crash have been met.
