摘要： The invention relates to a demolition hammer and/or hammer drill comprising a percussion generating device having a percussion piston moving axially back and forth. In a main percussion mode, the percussion piston impinges upon a tool which can move along a limited axial path straight into a main percussion direction. In a free percussion mode, the percussion piston indirectly impinges upon a percussion changing device, and by means thereof upon the tool, in a free percussion direction opposite to the main percussion direction. The impact surface of a tool shaft and the impact surface of a free percussion ram are placed opposite an impact surface of the percussion piston in such a way that the free percussion ram is removed from the effective area of the percussion piston by a return spring in the main percussion position. Under the effect of the return spring, the percussion ram is simultaneously supported on a gear member of the percussion changing device, which projects with an extension into the motion path of a stop surface provided in the tool. The stop surface reaches the extension when it has moved away from the effective area of the percussion piston in an idle running state of the tool shaft. If the movement of the tool is continued, the stop surface impinges upon the gear member against the effect of the return spring and relocates the free percussion ram in the effective area of the percussion piston by overcoming the spring force.

摘要： The invention relates to a safety arrangement for a vehicle, in particular for a motor vehicle with an airbag (2), folded together in the non-activated basic state, which on a triggering of the safety arrangement (1) by an activation signal is able to be inflated with different volumes in the direction of the interior of the vehicle by means of a gas generator (3), and with a crash sensor system which detects a vehicle impact and emits the activation signal for this. According to the invention, the crash sensor system comprises both a pre-crash sensor system and also an in-crash sensor system, wherein the pre-crash sensor system generally already detects an impending collision before an actual impact, and for this circumstance emits a pre-crash activation signal as activation signal. The in-crash sensor system detects an actual impact and for this circumstance emits an in-crash activation signal (backup) if the pre-crash sensor system has previously not detected the impending collision and has not emitted a pre-crash activation signal. The airbag is able to be inflated to a larger airbag volume (FIG. 1; Volume A+B) and to a relatively smaller airbag volume (FIG. 2; Volume A) by comparison, wherein by a pre-crash activation signal in a pre-crash mode the inflation process is activated for the larger airbag volume (FIG. 1; Volume A+B), and by an in-crash activation signal in an in-crash mode the inflation process is activated for the relatively smaller airbag volume (FIG. 2; Volume A).

摘要： A safety arrangement for a motor vehicle includes an airbag and a crash sensor system. The airbag is normally folded together in a non-activated basic state and is able to be inflated with different volumes. The crash sensor system detects a vehicle impact and emits an activation signal. The crash sensor system includes both a pre-crash sensor system and also an in-crash sensor system, and emits a pre-crash activation signal as activation signal upon detection of an impending collision. The in-crash sensor system detects an actual impact and emits an in-crash activation signal (backup) if the pre-crash sensor system has previously not detected the impending collision and has not emitted a pre-crash activation signal. The airbag may be inflated to a larger airbag volume and to a relatively smaller airbag volume in an in-crash mode.
