<p>A vehicle securable attachment (10) via which a vehicle seat is attached to a vehicle to render it rearwardly swivellable in the case of rapid vehicular deceleration comprises a pair of rails (12) along which a vehicle seat (14) is moveable up to a position of stoppage by being fitted to each rail via a carrier arrangement (16) providing runners (20) engaging rollably to the rails (12). The runners (20) are maintained in the position of normal seating by means of a shear pin (18) passing along registering apertures (19) in the runners (20) and the rails (12). The stoppage position of each runner (20) along its rail (12) is formed by a stopper pin (28). The rails (12) extend between legs (30) used for operatively bolting or otherwise securing the attachment (10) to the floor of a vehicle. Operative location of the attachment (10) involves its anchoring via conventional seat to vehicle body anchoring means. The seat (14) is securely fitted via its base engaging support (32) to the runners (20). Once a vehicle fitted with the adapted seat (14) is subject to rapid deceleration force, the shear pin is sheared resulting in the rapid forward movement of the carrier arrangement (16) and seat (14) assembly. The arcuate shape of the rails (12) simultaneously causes the seat to swivel in the direction of arrow (44).</p> |
