Abstract: A lock plate and a movable plate are provided to fix a seat at an optional position, and an actuator is provided between the seat and the movable plate. The seat is moved to the rear of a vehicle body in an initial stage of impact by the actuator. Acceleration is generated in the seat through impact abutment of a collapsible tube in the actuator against a piston head in an intermediate stage of impact. In a final stage of the impact, the seat is made integral with the vehicle body. The deceleration of the vehicle body and the seat and the deceleration of an occupant can be made equal to each other at an earlier timing. The apparatus can be installed by making use of a space under the seat, whereby the necessity of securing a special vacant space for installation of the apparatus can be obviated.

Abstract: An impact force is applied to a sensing element to enlarge the size of a hidden crack to a visible level to reveal the presence of a hidden crack. To apply the impact force to a sensing element, a gas sensor is supported by a holder which is fixed to a distal end of a shaft. The shaft swings about a proximal end thereof serving as a pivot. The holder, with the gas sensor held at its end, is released from a predetermined higher position so as to swing downward about the pivot of the shaft due to gravity. The holder hits a striking plate disposed on a swing path of the holder.

Abstract: As a moveable part of the vehicle body carrying a vehicle seat moves rearward under the action of an active or passive power source as a result of a vehicle crash, the seat belt which is anchored at the moveable part at one end and a fixed part of the vehicle body at another end is pulled rearward, and performs the function to apply a deceleration to the vehicle occupant in an early phase of the vehicle crash. This is followed by a slight slackening of the seat belt as the moveable part is subjected to a forward force. The active power source typically consists of a high pressure gas generating device, and a passive power source typically consists of a G control member which transmits the deceleration of a vehicle crash to the vehicle occupant from an early phase of the crash, and/or a stopper which applies a forward force to the moveable part as the moveable part moves rearward by a prescribed distance under the action of the power source.
