Abstract 1,070,035. Latch fastenings. "SOCIETE D' ETUDES & DE RECHERCHES TECHNIQUES" (S.E.R.T.). Sept. 23, 1964 [Sept. 25, 1963], No. 38749/64. Heading E2A. In a mechanism for latching vehicle doors, an energy storage device comprises a blade spring 21 which is loaded by an arm 16 pushing a leaf 19 solely under the closing action of the door. When the door is very nearly closed, the leaf 19 pushes a slide 28 to cause a pawl 23 to release a second leaf 18 whereupon the spring 21 urges upward a rod 8. A stop 30 rises to contact the arm 16 behind a block 31 to hold the arm, Fig. 6 (not shown). The upward movement of the rod 8 causes a piston (39); Fig. 7 (not shown) to force hydraulic fluid from a cylinder (38) to a cylinder (44) thereby pushing a ball (47), mounted on a latch bolt (46), into engagement with a keeper on the door post, Fig. 8 (not shown). An annular shoulder (54) on the keeper cooperates with an opening (55) on the end of cylinder- (44) to provide an antiburst device. An inner door handle (13) releases the stop 30 and opens a ball valve (58), Fig. 7 (not shown), enabling the door to be opened and the mechanism to return to its initial condition. A childsafety lock may be incorporated. The motion transmitting means may be solely mechanical or solely hydraulic.
