Patent ID: 7570429

Claim:
An emergency mechanism for moving an element in a vehicle from a deployed position to an emergency position in a state of emergency, said element being firmly coupled with said emergency mechanism, said emergency mechanism being pivotally coupled with a deployment mechanism of said element by a cam pivot, said emergency mechanism comprising: a lever, having a first end and a second end; a spring, having a first end and a second end, said first end of said spring firmly coupled with said emergency mechanism, said second end of said spring coupled with said first end of said lever; a cam follower, coupled with said second end of said lever, a cam, firmly coupled with said deployment mechanism, said cam pivot passing through said cam, said cam further including: a tapering section, having a first side and a second side, said cam follower being pressed against said first side of said tapering section when said element is in said deployed position, said cam follower being pressed against said second side of said tapering section when said element is in said emergency position; a stopping arm, said stopping arm extending outward of said cam, distant from said tapering section; a deployed stopper, located on the one side of said stopping arm, for stopping said emergency mechanism when said element is in said deployed position, and an emergency stopper, located on the other side of said stopping arm, for stopping said emergency mechanism when said element is in said emergency position, when in said state of emergency, said vehicle decelerates with a deceleration greater than a predetermined value, causing said cam follower to roll along an edge of said tapering section, said spring pressing said cam follower against said second side of said tapering section, thereby rotating emergency mechanism and said element around said cam pivot, until said stopping arm contacts with said emergency stopper, and said element is located away from an operator of said vehicle.
