Vehicle seat

Claim 2

A vehicle seat comprising: a pair of base brackets fixed on the floor of the vehicle, a pair of support brackets fixed to opposite sides of a cushion, a pair or lock members, a transversely extending connecting rod rotatably journaled to the support brackets and fixedly connected at its end portions to the respective lock members, said connecting rod including a crank-like handle portion formed at an intermediate portion of the connecting rod and operable to disengage the lock members from the base brackets.

Claim 3

The vehicle seat as claimed in claim 1, wherein said crank-like handle portion is provided with a slippage-preventive cover.

Claim 4

The vehicle seat as claimed in claim 1, wherein, when said seat is in the locked state with regard to said floor, said crank-like handle portion is positioned in a manner depending generally perpendicularly from a longitudinal axis of said connecting rod, whereby rotating said crank-like handle portion from said perpendicular position to a horizontal line causes disengagement of said lock means out of said base bracket, thus releasing said locked state of said seat and permitting removal of said seat from said floor.

Claim 5

The vehicle seat as claimed in claim 1, wherein said pair brackets are fixed on the reverse side of said seat cushion such that they are disposed on respective both lateral sides of and forwardly of said seat cushion, wherein said pair of lock members are each provided inwardly of and adjacent to the respective two support brackets, wherein said pair of support brackets are each formed with an engagement recess at its forward edge, wherein said pair of lock members are each formed at its forward portion with a latch hook part and further are at their respective rearward portions fixed on said connecting rod, wherein both ends of said connecting rod are supported rotatably in said pair of support brackets, wherein said pair of lock members are normally biased by spring means in a direction in which their latch hook parts are engaged over said connecting rod, wherein said base bracket comprises a pair of base brackets which are disposed at point corresponding to that of said two support brackets, said pair of base brackets being each provided with a support pin, and wherein normally, said support pins of said base brackets are encircled by said two latch hook parts of said lock members as well as said two engagement recesses of said support brackets, to thereby lock said seat to said two base brackets on said floor, and when said crank-like handle portion of said connecting rod is rotated, said two latch hook parts of said lock members are caused to rotate about an axis of said connecting rod in a direction away from the respective said two support pins of said base brackets, thereby allowing sliding-out of said two engagement recesses from said support pins and thus removal of said seat cushion from said base brackets.
