摘要:
A fail-safe electromagnetic linkage has a support device (108) for a valve head (102), and an actuator component actuable by an actuator. The support device is coupled to the actuator component whilst power is supplied to the electromagnet (140) and decoupled from the actuator component whilst power is not supplied to the electromagnet.

A drive device comprising a rotatable driving shaft and driven shaft (1,2). The driving shaft and driven shaft (1,2) are joined to each other by means of a magnetic coupling (5). The driven shaft (2) can be blocked in a direction of rotation such that magnetic forces emanating from the magnetic coupling (5) cause the driven shaft (2) to move in a direction opposite that of the direction of blocking. The driven shaft (2) moves in a springing manner.

A restraint apparatus 10 for protecting a vehicle occupant in a side impact or rollover event. The restraint apparatus 10 includes a deployment guide 21 that includes a housing having a channel 30 with a substantially smoothed interior 33 and longitudinal slot 32. A guide member 21 is slidably retained in the channel 30 and has an extension 20 protruding from the slotted side of the channel 30. The extension 20 is attachable to a restraint device 12 deployable laterally of a vehicle occupant. An actuator 18 is provided and is operable to drive the guide member 21 from a first end of the channel 30 toward a second end. A driving of the guide member 21 facilitates deployment of the restraint device 12 and supplies at least a longitudinal tensioning force to the restraint device 12 to provide lateral support thereto.

The invention relates to a energy accumulator for a sequence switch, provided with a lifting carriage (8), which may be operated by a drive shaft and a driven piece (9), which in turn operates a drive shaft connected to the transfer switch. Between both components, tensioning springs (10) are conventionally located. Both components are longitudinally guided along guide rods (6, 7), arranged laterally one below the other. The driven piece (9) is toothed, the longitudinal movement of which after release is directly transformed into a rotational movement of the drive shaft (28), by means of said toothing and a meshed gear wheel (27).

A force sense imparting type input apparatus includes an operation portion (3), an actuator (5) for imparting a force sense to the operation portion (3), a position sensor (6) for detecting an operating direction and an operating quantity of the operation portion (3), a temperature sensor (7) for detecting a temperature of the actuator (5), and a controller (8) for acquiring a position signal (a) and a temperature signal (b) and outputting driving signal (c) of the actuator. A correction control portion (8c) provided to the controller (8) determines a calorific value of the actuator (5) from the temperature signal (b), then a correction value (e) of driving power supplied to the actuator from the calorific value so calculated, adds a correction value of driving power of the actuator at the time of a normal operation and decides driving power of the actuator (5) at the time of over-heat.

The invention relates to a device for repositioning a rotating element in a defined base position. Said device comprises a spatially fixed cam (13) and a driving cam (14) which is coupled to the rotating element and can be moved in front of the fixed cam (13), each cam comprising a stop face (131, 132, 142) on opposite sides. The inventive device also comprises a clip spring (18) which clips the cams (13, 14) in a prestressed manner with two bent spring legs (181, 182). In order to ensure that there is no rotational play between the clip spring (18) and the cams (13, 14) in the base position, in at least one section of the spring leg (181) extending over the stop faces (141) of the cam, an elastic spring element (19) is provided, said spring element supporting the associated stop face (141) with a spring force which is smaller than the prestress force of the clip spring (18).

This invention relates to windshield wiper system (10) and method which utilizes a flexible member (28) to account for compression loads in excess of a predetermined load, such as 30 percent greater than a maximum load for the flexible member (28). The system (10) utilizes a flexible pultruded composite material having a relatively low modulus of elasticity, yet relatively high elongation characteristics. The flexible arm (28) bends to facilitate preventing damage to components in the wiper system (10) when a compressive load applied to the flexible member (28) reaches a predetermined load as a result of a fatigue condition, such as snow or ice build up on the windshield (16). In one embodiment, the predetermined load is defined as: PCR = KE = 1.3Plink; where: PCR = the predetermined load; Plink = a maximum normal running load for a comparably-sized steel or rigid link which does not flex; K is a coefficient = E is the flexural modulus (MPa) and I is a moment of inertia in mm4 and L is a length (mm) of flexible arm (28).
摘要:
A lever arrangement to transmit a driving force to a switch contact of a power switch has parallel bearing plates (43, 44) and limiters (51, 52) secured thereto by means of which the distance between the bearing plates is locally reduced to one suitable for guiding articulated levers. Hinge pins (54) of the levers are supported so as to slide on the limiters (51, 52). Threaded pins (46) are riveted on one side to one bearing plate (43) and secured to the other bearing plate (44) by a nut (50).
