A rotation of the lifter link in a rear direction is restrained by a loosely fitted portion of the stopper link contacting an inner circumferential part of the long hole. A rotation of the lifter link in a front direction is restrained by a restraining contract part provided to the lifter link contacting a stopper part provided to the floor-side member. The restraining contact part is provided at a further outer side in a rotationally radial direction than a position of a front-side end portion of the long hole, with respect to a rotatable shaft support point of the one side of the lifter link. | 02-09-2012 |
20120097822 | SEAT SUSPENSION ARRANGEMENT AND METHOD FOR PRESTRESSING A GUIDE ASSEMBLY - A seat suspension arrangement includes an upper structure for receiving a seat and a lower structure for mounting the seat in a work machine or vehicle. The tipper structure and the lower structure are interconnected by at least one intermediate structure and displaceable towards and away from each other. The seat suspension arrangement includes a guide rail and a guided member which is connected to the intermediate structure and arranged at the guide rail.
