A liftable driver's seat for automobiles is provided which comprises a seat frame having generally a rectangular shape, bearing blocks disposed near each corner of the seat frame, links pivotally connecting the bearing blocks to the automobile floor, a main rotary shaft rotatively supported by one of said bearings at the front side, a pair of operating links pivotally connected together at their upper end portions, the lower end portions being fixedly secured to the main rotary shaft and pivotally connected to the link, respectively, which pivotally connects the bearing block that rotatively supports the main rotary shaft, a manipulating lever secured to the main rotary shaft, and operating lever disposed within the manipulating lever so as to actuate a stopper, and a counter member secured to the bearing block which rotatively supports the main rotary shaft and adapted to coact with the stopper.
A liftable driver's seat for automobiles comprising a seat frame having substantially a rectangular shape in the plan view, bearing block means disposed near the four corners of said seat frame so as to be rigidly secured thereto, link means pivotally connecting said bearing means to the floor of said automobile so as to be elongated in substantially the same direction, a main rotary shaft means rotatably supported by one of said bearing blocks, a pair of operating links pivotally connected together at one of their end portions, with the other end of one of said operating links being fixedly secured to said main rotary shaft, the other end of the other of said operating links being pivotally connected to one of said link means disposed near said bearing block which rotatably supports said main rotary shaft, and a manipulating lever means having generally a hollow cylindrical form and detachably secured to said main rotary shaft, said manipulating lever means is provided with a stopper means which is adapted to coact with a counter element secured to said bearing block which rotatively supports said rotary shaft such that said stopper means usually prevents said rotary shaft from being rotated in association with said counter element, but whereby, when said stopper means is separated from said counter element, said main rotary shaft is allowed to be rotated by said manipulating lever means.
A liftable driver's seat for automobiles comprising a seat frame having substantially a rectangular shape in the plan view, bearing block means disposed near the four corners of said seat frame so as to be rigidly secured thereto, link means pivotally connecting said bearing means to the floor of said automobile so as to be elongated in substantially the same direction, said link means arranged forward so as to confront each other are connected together by a rotary shaft secured thereto which is rotatably supported at its both ends by said bearing blocks which are disposed forward on said seat frame so as to confront each other a main rotary shaft means rotatably supported by one of said bearing blocks, a pair of operating links pivotally connected together at one of their end portions, with the other end of one of said operating links being fixedly secured to said main rotary shaft, the other end of the other of said operating links being pivotally connected to one of said link means disposed near said bearing block which rotatably supports said main rotary shaft, and a manipulating lever means having generally a hollow cylindrical form and detachably secured to said main rotary shaft.
