Provided is a clutch unit, including: a lever-side clutch section (11) provided on an input side, for controlling transmission and interruption of a rotational torque to be input through lever operation; and a brake-side clutch section (12) provided on an output side, for transmitting the rotational torque from the lever-side clutch section (11) to the output side, and interrupting a rotational torque to be reversely input from the output side. The brake-side clutch section (12) has a two-layer structure, in which two one-way clutches (50) and (51) are arranged side by side in an axial direction. The one-way clutch (50) on one side is configured to interrupt a rotational torque in a forward direction, which is reversely input from the output side, through meshing of serrated projection and depression portions (23a) and (27a), whereas the one-way clutch (51) on another side is configured to interrupt a rotational torque in a backward direction, which is reversely input from the output side, through meshing of serrated projection and depression portions (33a) and (37a) arranged in an opposite direction to that of the projection and depression portions (23a) and (27a). Accordingly, the brake-side clutch section (12) serves as a two-way clutch.

The invention relates to a mine-safe seat device (10) having tubes (2) for connecting to a vehicle roof (3) or to a vehicle floor. An additional tube (4) is placed over the seat device (10) as a seat slide, which has notches for a detent (8) on the outside of said tube. An additional tube (7), to which the actual seat (1) is fastened, is placed over said seat slide (4). The detent (8) is integrated on the tube (7) placed over the seat slide (4). The detent is preloaded so that when a force that cancels out the preload is reached, the detent (8) slides further downward along the notches of the seat slide (4) and releases additional travel.

In the manufacturing process of a vehicle seat S, deformation of one-end-side frame 6a made of CFRP in a seat cushion frame 2 is suppressed, when a first revolving arm 33 of a rear side link 30 is assembled to the one-end-side frame 6a, by a portion provided with a metallic sector gear 31. In a vehicle seat S having a seat cushion frame 2 and a rear side link 30 including a metallic sector gear 31, a first revolving arm 33 of the rear side link 30 is assembled to the one-end-side frame 6a made of CFRP in the seat cushion frame 2. Furthermore, in order to assemble the first revolving arm 33 to the one-end-side frame 6a, a first shaft pin 61 made of metal is inserted into both a link assembling hole 51 of the one-end-side frame 6a and a pin hole 31b of the sector gear 31 in a state in which the holes 51 and 31b communicate with each other, and the first shaft pin 61 is fixed by welding to the sector gear 31 in a state in which a flange portion 61b is locked to the one-end-side frame 6a.

Fitting for an adjusting device of a motor vehicle seat and a method for the production thereof. The invention relates to a fitting (1), more particularly for an adjusting device of a motor vehicle seat, with a fitting top part and a fitting bottom part (3) adjustable relative to the fitting top part (2), a transmission gear unit, which is in operative connection with the fitting top part and fitting bottom part, for adjusting the fitting top part relative to the fitting bottom part, and a drive shaft (21) extending at one end through the fitting in a longitudinal axial direction of a fitting axis and in engagement with the gear unit. The invention also relates to a method for producing a fitting of the type mentioned above. To provide a fitting and a method for producing a fitting that ensures, even under elevated loads, a reliable arrangement of the fitting parts relative to one another, the invention provides wobble riveting the drive shaft (21) at one end to a bushing (6) to secure the axial position of the fitting top part (2) relative to the fitting bottom part (3), said bushing being arranged in an opening (11), arranged coaxially to the fitting axis, of the fitting top part or fitting bottom part, the drive shaft resting, on the side opposite the bushing, with a stop (12) against the fitting.

Vehicle seat including a link for raising and lowering the seat and a tilt pan disposed forwardly of seat cushion frame of the seat. Rotatably provided to the seat cushion frame is an actuator link having: one end portion pivoted to the tilt pan; and another end portion formed with sector gear portion and arcuate hole. A pin for supporting a gear case having a pinion meshed with the sector gear portion is fixed to the seat cushion frame. Such pin is used with both of the link and actuator link, in common. Namely, an upper end portion of the link and the afore-said another end portion of actuator link are collectively disposed at that pin so as to overlap each other, and the upper end portion of link is pivotally connected to the pin, whereas the pin passes through the arcuate hole of actuator link.
