Abstract: A linear drive, especially for a belt tensioner, includes a housing (10) including a piston seat (12), a piston element (16) accommodated in the piston seat (12) and a pyrotechnical drive element adapted to supply gas for displacing the piston element (16). The inner wall of the piston seat (12) includes a groove (30) extending in the displacing direction (R) of the piston element (16) through which gas can flow off the piston seat (12).

Abstract: A positioning device has a deformable load-bearing element (10), a shaped part (12) coupled to the load-bearing element (10), and a holder (24). The load-bearing element (10) is adapted to be shifted from a first position in which the shaped part (12) is held in a first shape by the holder (24), into a second position in which the shaped part (12) is at least partially no longer held by the holder (24) and takes a second shape which is transmitted to the load-bearing element (10).

Abstract: A deflection fitting for vehicular safety belt systems comprises a yoke with a pair of parallel limbs interconnected by a rod and a roller rotatably mounted on the rod. The roller has a cylindrical main section between a pair of axial end sections. A substantially continuous and concavely curved transition is provided from the main section to each end section of the roller and from each end section to an adjacent limb surface portion.

Abstract: A safety closure cap having a first closure member and a second closure member rotatably retained therein. The second closure member may be screwably attached to a container, so that the cap closes the container by rotation of the first closure member in the closing direction, the two closure members being coupled together for this purpose. For removing the cap from the container the cap is provided with a further coupling arrangement which can be engaged when the two closure members are moved together, rotation of the first closure member in a direction opposite to the closing direction causing simultaneous screwable rotation of the second closure member from the container.

Abstract: A safety screw closure for use with a container having an inner screw cap on to the bottom edge of which an elastically expandable securing ring is attached by at least one rupturable bridge member. An outer cap is mounted on the inner cap and slidable axially between a first position remote from the inner cap and second position. A spring is located between the caps to normally urge the outer cap into the first position. The caps are provided with at least one set of cooperating coupling means which are in cooperation in any axial position of the outer cap when the closure is screwed on to the container whereas they are ineffective when rotating the outer cap in the opposite direction and when the outer cap is ints first position in which it is not depressed against the spring. The outer cap being dimensioned so that when in the first position it extends above the securing ring.
