Locking mechanism for a seat frame

摘要

A locking mechanism for a foldable seat frame pivotable about a forward pivot axis attached to a chassis is provided. The rear area of the seat frame may be secured in a locked position by means of a stop bolt that passes through an opening attached to the chassis and by means of spreader devices that may move radially inward and outward and that engage behind the edge of the opening. A displacement body for the spreader bodies may be displaced by means of an actuation lever pivotable on the rear 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. The actuation lever is mounted so that it may be displaced longitudinally against the force of the securing spring, 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.
