<p>PROBLEM TO BE SOLVED: To restrain a seat from sinking immediately after the occurrence of a rear collision of a vehicle and thereby prevent buckling of the seat with an inexpensive structure.SOLUTION: In a vehicle seat height adjustment device, a restraining body 10 is disposed at the rear side of a second link body 3a2. The second link body 3a2 is restrained from rotating to the rear side by the restraining body 10 contacting with a rear surface of the second link body 3a2. Thus, in a rear collision of a vehicle, the vehicle seat height adjustment device inhibits the seat 5 from sinking and prevents buckling at a current position by using an inexpensive structure without allowing the seat 5 to move to a lowest position as in a conventional seat.</p> |
