Embodiment Construction

[0038] Hereinafter, embodiments of a vehicle seat for carrying out the present invention will be described with reference to the drawings. figure 1 It is a side view schematically showing the raising mechanism 30 before raising. figure 2 It is a side view schematically showing the raising mechanism 30 after raising. in addition, figure 1 and figure 2 It is a figure which schematically shows the raising of the seat cushion 11 in the vehicle seat 10, Especially, it shows so that the cushion frame 12 and the raising mechanism 30 may understand easily. Thus, in figure 1 and figure 2 In FIG. 2 , the cushion frame 12 , the lifting mechanism 30 , and the slide rail mechanism 20 are highlighted, and the illustration of the other structures of the vehicle seat 10 is omitted. In addition, in figure 1 and figure 2 In the drawing, the left side in the figure is set as the front of the vehicle seat 10 , and the right side in the figure is set as the rear side of the vehicle seat...

Abstract

When rotating with fixed end-side axis parts (43, 53) set as rotational axis fulcrums, rotating end-side axis parts (45, 55) of a forward link (41) and a rear link (51) move in an up-down direction. The range of rotation of the forward link (41) is arranged in a manner such that the rotating end-side axis part (45) of the forward link (41) is always above a rotation center joining line (L). The range of rotation of the rear link (51) is arranged in a manner such that the rotating end-side axis part (55) of the rear link (51) is in a range that straddles the rotation center joining line (L). As a result, the rotating end-side axis part (45) of the forward link (41) is lowered, and only the rotating end-side axis part (55) of the rear link (51) is raised, until the point where a rotating end joining line (M) switches from a below-side position to an above-side position relative to the fixed end-side axis part (53) of the rear link (51). Hence, it is possible to effectively lift a seat cushion upward when a passenger gets in or out of a vehicle, in a manner such that the position of the hips of the passenger are higher relative to the position of the knees of the passenger.

Description

technical field [0001] The present invention relates to a vehicle seat installed on vehicles such as automobiles. More specifically, the present invention relates to a vehicle seat in which a seat cushion can be raised when passengers get on and off the vehicle. Background technique [0002] A vehicle seat for passengers to sit on is arranged on the compartment panel of the automobile. The vehicle seat includes a seat cushion for a passenger to bend down and sit down. Among such vehicle seats, there is known a vehicle seat provided with an elevating mechanism capable of changing the height position of a seat cushion for bending over. In the vehicle seats disclosed in Patent Document 1 and Patent Document 2 below, a pair of links (a front link and a rear link) in the width direction are arranged in front and rear of the seat cushion. Like a general link structure, the base end sides of the front link and the rear link are connected so as to be rotatable relative to the bas...
