SLIDE STRUCTURE OF SEAT FOR VEHICLE
First Claim
1. A slide structure of a seat for a vehicle which positions a cushion seat in the longitudinal direction of the vehicle comprisesa stationary outer rail which extends in the longitudinal direction of the vehicle and includes a substantially C-shaped cross section an open portion of which is oriented to be inner in the widthwise direction, and is disposed in such a way that its cross section is elongate in the vertical direction,a movable inner rail which extends in the longitudinal direction of the vehicle and fits over the stationary outer rail so as to be slid relative to the stationary outer rail in the longitudinal direction and is fixed on the cushion seat and includes a substantially C-shaped cross section an open portion of which is oriented to be outer in the widthwise direction, and is disposed in such a way that its side surface is elongate in the vertical direction, whereby the movable inner rail fits with the stationary outer rail in such a way that open portions formed by the respective C-shaped cross sections are opposed to each other, so that in a case where the cushion seat is located to be in the most front position, the front end of the movable inner rail protrudes forward from the front end of the stationary outer rail, while, in a case where the cushion seat is located to be in the most rear position, the rear end of the movable inner rail protrudes rearward from the rear end of the stationary outer rail,said slide structure further comprises a parallelogram link mechanism rotatable about a horizontal axis including a front link and a rear link parallel to each other one end of each of which is pinned to the cushion seat, while the other end of each of which is pinned to the side surface of the movable inner rail, anda means for adjusting the widthwise position which functions to adjust the relative positional relationship in the widthwise direction between the movable inner rail and the front link or the rear link in such a way that the shear load transmitted from the front link or the rear link passes through the shear center situated to be inner in the widthwise direction of the side surface of the movable inner rail.

Abstract
A slide structure of a seat for a vehicle positions a cushion seat in the longitudinal direction of the vehicle has a stationary outer rail which extends in the longitudinal direction of the vehicle and a substantially C-shaped cross section, an open portion which is oriented to be inner in the widthwise direction, and is disposed such that its cross section is elongate in the vertical direction, a movable inner rail which extends in the longitudinal direction of the vehicle and fits over the stationary outer rail so as to be slid relative to the stationary outer rail in the longitudinal direction and is fixed on the cushion seat and includes a substantially C-shaped cross section, an open portion of which is oriented to be outer in the widthwise direction, and is disposed in such a way that its side surface is elongate in the vertical direction.

8. A slide structure of a seat for a vehicle which positions a cushion seat in the longitudinal direction of the vehicle comprises
a stationary inner rail which extends in the longitudinal direction of the vehicle and includes a substantially C-shaped cross section an open portion of which is oriented to be inner in the widthwise direction, and is disposed in such a way that its cross section is elongate in the vertical direction, a movable outer rail which extends in the longitudinal direction of the vehicle and fits over the stationary inner rail so as to be slid relative to the stationary inner rail in the longitudinal direction and is fixed on the cushion seat and includes a substantially C-shaped cross section, and is disposed in such a way that its side surface is elongate in the vertical direction, whereby the movable outer rail fits with the stationary inner rail in such a way that open portions formed by the respective C-shaped cross sections are opposed to each other, so that in a case where the cushion seat is located to be in the most front position, the front end of the movable outer rail protrudes forward from the front end of the stationary inner rail, while, in a case where the cushion seat is located to be in the most rear position, the rear end of the movable outer rail protrudes rearward from the rear end of the stationary inner rail, said slide structure further comprises a parallelogram link mechanism rotatable about a horizontal axis including a front link and a rear link parallel to each other one end of each of which is pinned to the cushion seat, while the other end of each of which is pinned to the side surface of the movable outer rail, and a means for adjusting the widthwise position which functions to adjust the relative positional relationship in the widthwise direction between the movable outer rail and the front link or the rear link in such a way that the shear load transmitted from the front link or the rear link passes through the shear center situated to be outer in the widthwise direction of the side surface of the movable outer rail.
