    • A suspension seat for an automotive vehicle has a seat frame which is vertically movably supported on a parallel link mechanism. A compression spring and a shock absorber of a suspension unit are coaxially assembled. A spring bracket is disposed on the compression spring and screwed with a rod of the shock absorber. A fixing nut is fixed to the rod on the spring bracket to adjust elastic force of the compression spring by changing the position of the spring bracket. A projection of the spring bracket projects from a slit of a suspension unit support bracket with scale division. A resilient bracket supports the parallel link mechanism and outwardly projects to function as a bumper for a seat frame. Therefore, the suspension seat suppresses shock or sound due to impact during an operation of the seat and realizes a simple adjustment of hardness of the suspension unit.
    • 一种用于机动车辆的悬挂座椅具有可垂直移动地支撑在平行连杆机构上的座椅框架。 悬挂单元的压缩弹簧和减震器被同轴组装。 弹簧支架设置在压缩弹簧上并与减震器的杆螺纹连接。 固定螺母固定在弹簧支架上的杆上,通过改变弹簧支架的位置来调节压缩弹簧的弹力。 弹簧支架的突起从刻度尺的悬挂单元支撑支架的狭缝突出。 弹性支架支撑平行连杆机构,并向外伸出,用作座椅框架的保险杠。 因此,在座椅的操作中,由于冲击而使悬架座体抑制冲击或声音,因此实现了悬架单元的硬度的简单调整。

    • A seatback frame (21) is disclosed as having an inverted U-shaped frame member (22) including an elongated and generally horizontal upper member (23) and a pair of elongated side members (24) and (25) respectively extending generally downwardly from the extremities of the upper member. A pair of side panels (28 and 29) are respectively secured to and extend generally forwardly from each side member and have inwardly facing surfaces that oppose each other. A resilient lumbar supporting panel (35) having lateral extremities is forwardly spaced from the side members proximate the side panels and is generally concave therebetween. It has a central portion that extends generally upwardly and is secured to a central portion of the upper member. The lateral extremities form retrorse portions (41) that extend generally rearwardly along the opposed surfaces of the side panels, and the rearmost margins (43) of the retrorse portions are attached to the side panels. The resilience of the lumbar supporting panel allows the retrorse portions to flex generally about their attached margins to damp any acceleration of a passenger toward the seatback frame of vice versa.

    • A seat arrangement of a forklift truck includes a hood for covering an engine, a seat mounted on the hood, a seat slide mechanism and a supporting member. A seat cushion of the seat is pivotally secured at its front end portion to an upper rail of the seat slide mechanism. The supporting member has a first end which is pivotally secured to an upper surface of the hood and a second end which is engageable with an engaging portion of the seat. When it is necessary to open the hood, the seat positioned at a certain position in a fore-and-aft direction is swung forwardly, then the second end of the supporting member is brought into engagement with the engaging portion of the seat to keep the seat at a certain angle defined between a bottom surface of the seat cushion and the upper surface of the hood, and then the hood is opened. As the seat is positioned more forward through the seat slide mechanism, the certain angle decreases so that the seat is prevented from abutment with a LP-gas cylinder and a head guard of the forklift truck when the hood is opened.
