Seat moving device for vehicle

Abstract

It is one object of this invention to provide a technique that is effective in diminishing the range of fluctuation of a load applied to a drive source when a seat main body in a vehicle seat moving apparatus is moved between a raised position and a lowered position. For this purpose, this invention provides a vehicle seat moving apparatus constructed as follows. Provided on a rotation base, for rotating a seat main bodybetween a position where it faces the front side of the vehicle and a position where it faces a door opening, is a widthwise slide basethat moves horizontally in the vehicle width direction while the seat main bodyfaces the door opening. The seat main bodyis supported by the slide basevia four-bar linkage mechanisms. Guide rollersare attached to upper link armsof the four-bar linkage mechanisms. The guide rollersare placed on cam surfaces of cam platesprovided to the rotation base. The cam surfaces have continuously extending inclined guide surfacesthat guide such that the guide rollersmove obliquely upwards when the widthwise slide basemoves.
