Abstract: An accelerator pedal for a vehicle, wherein a bracket secured to or forming part of the vehicular body is hinged to an upper rotary arm, a lower rotary arm and a connecting arm, preferably to constitute a quadric link. The connecting arm is adjusted in length thereof to allow a rotary center of a driver's foot stepping on the foot pad to correspond to that of a pedal arm, thereby enabling the accelerator pedal to at least approximate the rotary track of a driver's foot to discourage slippage of the driver's foot therefrom, and improve the manipulating stability and manipulability of the accelerator pedal.

Abstract: The present invention relates to a headrest assembly for protecting the neck of a vehicle seat occupant by preventing sudden movement of a head upon rear end collisions, and more particularly, to a headrest assembly for protecting the neck of a vehicle seat occupant, comprising the first actuating rod pivotally connected to the upper cross member of a seatback frame and rotatably installed inside the seatback, which moves the headrest forward upon rear end collisions in order to limit the backward movement of the head of a vehicle seat occupant, and the second actuating rod pivotally connected to the lower cross member of a seatback frame under the first actuating rod, wherein said actuating rods are linked by means of a sliding assembly.
