Knee restraint device for vehicles
First Claim
1. A knee restraint device for vehicles, comprising:
- a knee protector plate movable in the direction of the knees of a vehicle occupant,a gas generator,a base plate connectable to a vehicle structure having at least one opening for connection to said gas generator,a wall of flexible material with a first closed rim and a second closed rim,said wall being folded between said base plate and said knee protector plate in a resting condition and being connected along said first closed rim to said base plate and along said second closed rim to said knee protect-or plate,said knee protector plate having a first edge oriented in a vehicle transverse direction and a second edge located opposite said first edge,said first edge being held swivable and releasable on said base plate, anddefeatable fastening means for securing said second edge to said base plate,said flexible wall expanding in response to an increase in pressure upon activation of said gas generator, andwherein, when said flexible wall expands, said defeatable fastening means releases, such that further expansion of the flexible wall causes said knee protector plate to swivel about its first edge, whereby still further expansion causes said first edge to release from the base plate.

Abstract
A knee restraint device for vehicles comprises a knee protector plate movable in the direction of the knees of a vehicle occupant, a base plate connectable to a vehicle structure having at least one opening for connection to a gas generator and a wall of flexible material folded between said base plate and said knee protector plate in the resting condition. Said wall is connected along a first closed rim to said base plate and along a second closed rim to said knee protector plate. To control the movement path of the knee protector plate during the inflation action a first edge of said knee protector plate oriented in the vehicle transverse direction is held swivable and releasable on said base plate and a second edge of said knee protector plate located opposite said first edge is secured to said base plate by a fastener which releases on activation of said gas generator due to the expansion pressure of said wall being deployed. The fastener releases before said knee protector plate has swivelled about its first edge and has been subsequently released from said base plate.
