Abstract: A firing mechanism for a pistol comprises a firing pin, a hammer for striking on the firing pin, a hammer spring biasing the hammer, and a catch lever for temporarily locking the hammer in a cocked position is designed to have a safety function. In order to provide a structurally simple mechanism which provides perfect safety against an unintended discharge of a shot without need for additional parts, the catch lever is provided with two locking surfaces. When the hammer is uncocked, the firing pin bears on one of said locking surfaces in the firing direction and the hammer bears on the other of said locking surfaces in the striking sense.

Abstract: A kick-down circuit for an automatic change-speed transmission with a kick-down control member transmitting a kick-down control signal when an accelerator or gas pedal is floored and with at least one gearshift control element operating in dependence upon a transmission output speed and a position of the gas pedal for an auxiliary operating force of a shift actuating member participating in a shifting between a higher gear and a lower gear. The gearshift control element, upon an occurrence of the kick-down control signal, may be brought into its position for the lower gear under the effect of an auxiliary control force dependent upon a position of the gas pedal. The kick-down control signal is temporally limited independently of the position of the gas pedal.

Abstract: A multiple-link gas pedal of a synthetic resionous material for a motor vehicle. The links of the gas pedal are joined by hinge-like film hinges integral in the material. A connecting member for a hinged connection of the foot plate with a pivotal lever suspended into a foot space is arranged in a zone of an upper end of the foot plate on a rear side thereof. A mounting member is articulated to the connecting member through a further film hinge. The mounting member is provided with a bore for receiving the free end of the lever. The bore exhibits at least one flaring portion and a lower end of the lever exhibits projections corresponding in number and shape to the flaring portions. After a passing of the lever end through the bore, the constructional position is obtained by mutual twisting of the components, in such a way that the projections rest on the underside of the mounting member on marginal zones of the bore which are not widened.

Abstract: A short-circuit fuse for electrical igniters with a plug-in connection wherein the short-circuit is automatically eliminated upon a connection of the igniter to a current carrying line. At least one pin-shaped electrode, extending out of the igniter, is surrounded by a common socket with at least one contact spring, arranged at the socket and extending essentially in parallel to the at least one electrode, being normally in contact with the electrode when the igniter is unconnected to the current carrying line. The contact spring has an elongated and leaf-like shape and is electrically conductively connected with either a further contact spring or with the igniter casing. Upon a connection of the igniter to the current carrying line, the contact spring is lifted off the electrode by the insertion of a connector plug.
