In a thrust reverser translating mechanism, a drive shaft and a driven shaft are connected so as to permit a small degree of relative rotation. A pawl is pivotally connected to the driven shaft and an annular ratchet surrounds it. If the drive shaft controls the speed of rotation, it takes up the free movement and in so doing, moves the pawl out of engagement with the ratchet. If the driven shaft attempts to rotate faster than the drive shaft, it takes the pawl away from its engagement with the drive shaft and allows resilient means to urge the pawl into engagement with the ratchet thus stopping rotation of the driven shaft until the drive shaft catches up and disengages the pawl from the ratchet again.

A lock device for an output shaft, wherein an output shaft is formed by connection of a driving shaft and a driven shaft, a play angle for not transmitting power for a specified angle in mutual rotating directions is formed in the connection area for connecting the driving shaft and driven shaft, a locking mechanism for locking by moving a lock member arrested on the driven shaft and held movably inward and outward in the radial direction is provided at the driven shaft side, and an unlocking mechanism for unlocking by moving the lock member of the locking mechanism in an unlocking direction within the rotating amount of the play angle is provided in the driving shaft.

A torque transmission device which can rotate an output shaft for transmitting the rotation from the operation side to he device and cannot rotate the output shaft form the device side. The torque transmission device excels in the durability with less wear-out by preventing the generation of the load concentration by the line contact of each component.

This invention relates to an energy absorbing ratchet for a bidirectional no-back apparatus which includes in combination a fixed support, a rotatable input member and a rotatable output member. The input member includes an input plate which has integral therewith a pair of release pins. An output plate is coupled to the output member. The input plate and the output plate have a torque transmission device coupled therebetween. The fixed support has an energy absorbing means coupled to a ratchet ring. The ratchet ring is positioned between the input and the output plate. The output plate has thereon a pair of moveably mounted pawl members for cooperative engagement with the ratchet ring to thereby engage the ratchet ring when the no-back apparatus is at rest, and whenever a backdriving load is delivered from the output member to the output plate. The pawl members are released from the ratchet ring by the cooperative engagement with the release pins upon bidirectional rotation of the input member.

A compact and quiet-operating motor vehicle window drive has the following features: a first drive element or worm gear drives an entraining element with tangential play; a toothed rim is provided in a gear drive housing, axially concentric with the entraining element; a detent pawl that can engage the toothed rim in a self-locking pivot position is mounted in the manner of a toggle lever in the entraining element; a friction ring, with a first disengagement cam in front of and a second detent pawl cam behind the detent pawl, is mounted frictionally and rotatably in the gear drive housing in such a way that when motor drive occurs in "raise" mode, the friction ring is moved by the entraining element by means of the detent pawl which contacts the first disengagement cam and when motor drive occurs in "lower" mode, the friction ring is moved directly by the first drive element (worm gear); and when the entraining element is driven from the output side in the "lowering" rotation direction, the detent pawl can be engaged in a self-locking manner in the toothed rim by means of the second detent pawl cam.
