PCT No. PCT/DE91/00391 Sec. 371 Date Dec. 13, 1991 Sec. 102(e) Date Dec. 13, 1991 PCT Filed May 8, 1991 PCT Pub. No. WO91/17678 PCT Pub. Date Nov. 28, 1991.A safety belt buckle for receiving and locking an insertion tongue is comprised of a casing having an insertion slot, an insertion tongue that is slidably mounted in the insertion slot and has a cutout, a spring-loaded ejector, arranged in the insertion slot and acting on the insertion tongue, and a locking device mounted inside the casing and cooperating with the cutout of the insertion tongue for locking the insertion tongue in the insertion slot in a locking position of the safety belt buckle. Furthermore, a spring-loaded sliding key is guided within the casing and comprises a sliding key body and a key button The key button is slidably connected to the sliding key body. The sliding key cooperates with the locking device to unlock the safety belt buckle. A sensor spring is mounted between the sliding key body and the key button for holding the key button in an extended position relative to the sliding key body and essentially maintaining the extended position when acceleration forces occur in an unlocking direction of the safety belt buckle. The sensor spring also translates a relative displacement of the key button from the extended position in the unlocking direction, caused by manual actuation of the key button, into a release action of the locking device, whereby the sliding key body and the key button, when acceleration forces occur and when the key button is not actuated, is insertable into the casing in the unlocking direction of the safety belt buckle without releasing the locking device.
