<p>A longitudinal adjuster (3) for a vehicle seat (1), particularly a motor vehicle seat, has at least one first seat track (5) having catches (20) disposed in at least one row running in the longitudinal axis (x) of the seat. Each catch (20) includes a front flank (21a) and a rear flank (21a) in the longitudinal axis (x) of the seat, and at least one second seat track (8) that can be displaced relative to the first seat track (5) in the longitudinal axis (x) of the seat and locked to the same and at least two catch plates (12) for locking the first seat track (5) to the second seat track (8). The catch plates (12) are displaceably supported in the locking direction (z) in the second seat track (8) and comprise teeth (12b) for engaging in the catches (20) of the first seat track (5). Each tooth (12b) includes a front and a rear tooth flank (12d) in the longitudinal axis (x) of the seat. Each of the catch plates (12) includes exactly two teeth (12b) per associated row of catches (20). Two teeth (12b) belonging to different catch plates (12) act together with the row of catches (20) associated with said teeth (12b) for locking the first seat track (5) to the second seat track (8) with no clearance.</p> |
