LOCKING MECHANISM FOR SEAT FRAME

摘要

PROBLEM TO BE SOLVED: To prevent a locking mechanism from being released in an unintentional manner.

SOLUTION: In the locking mechanism of a foldable seat frame pivotable about a forward pivot axis 1b attached to a chassis 1 of a car in the horizontal direction, a rear area of the seat frame may be secured in a locked position by means of a stop bolt 3 that passes through an opening 1c attached to the chassis by means of spreader devices 3a that may move radially inward and outward and that engage behind the edge of the opening 1c. A displacement body 3b for the spreader bodies 3a may be displaced by means of an actuation lever pivotable on the rear seat area of the seat frame in such a manner that the spreader bodies may be so radially displaced inwards that they lie within the outer shape of the stop bolt in an unlocked condition. An actuation lever 5 is mounted so that it may be displaced longitudinally against the force of a securing spring 6, and so that a pivoting motion to release the stop bolt is only possible upon longitudinal displacement against the direction of vehicle travel overcoming the force of the spring.
