Abstract:
1. A sliding-type automobile seat comprising: a seat cushion frame; a slide rail mechanism for allowing said seat to be slidingly moved; slide lock mechanisms for causing said seat to be releasably locked at predetermined positions; a substantially U-shaped operating lever for causing said seat to be released from a locked state; and connection mechanisms for causing both end portions of said substantially U-shaped operating lever to said slide lock mechanisms; said slide rail mechanism comprising a pair of parallel lower rails mounted on a floor surface of an automobile, and a pair of parallel upper rails attached to a lower portion of said seat cushion frame and slidably engaged with the pair of parallel lower rails; each of said slide lock mechanisms comprising a lock member swingably mounted to a corresponding upper rail and urged upward at one end portion thereof by a spring, said lock member including first engaging member, and second engaging member provided at a corresponding lower rail; said first engaging member and said second engaging member being adapted to be releasably engaged with each other, to thereby cause said seat to be locked at the predetermined positions; each of said connection mechanisms comprising a connection member having means for stoppingly engaging said lock member; and said means for stoppingly engaging said lock member being engaged with said lock member, whereby said operating lever is connected, via said connection mechanisms, to said slide rock mechanism by one-touch operation; wherein said means for stoppingly engaging said lock member comprises a lower joint mounted on said connection member, and an upper joint fixed on said lower joint and extending along said lower joint in such a manner to allow a predetermined space said upper joint and said lower joint; said lock member comprises a receiving piece for receiving one end portion of said lower joint, a holding-down piece for holding down said lower joint in said space between said lower joint and said upper joint, and a leaf spring having a first spring portion for causing the one end portion of said lower joint to be pressed against said receiving piece to interposingly hold the one end portion of said lower joint therebetween, and a second spring portion for pushing up said upper joint in the space to cause said holding-down piece to be pressed against said lower joint; and said operating lever is connected via said connection member to said lock member after the lock member is attached to the corresponding upper rail.
