<p><P>PROBLEM TO BE SOLVED: To provide a seat slide device for vehicles, having an upper rail fixed to a seat and a lower rail fixed to a vehicle floor, which are bent so that the tangential direction of moving trajectory of the upper rail is steeply inclined relative to a horizontal direction as the upper rail goes to the rear, while improving operability in moving the seat forward without any discomfort. <P>SOLUTION: A coil spring 30 in a housing member 11 assists the seat moving forward by biasing force that increases as the upper rail 5 goes to the rear, in a range from a predetermined intermediate position to the rear end position of the upper rail 5, between the front end position and the rear end position of the upper rail 5. In the range, the upper rail 5 moves with respect to the lower rail 4. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
