Abstract:
A brake device for a cable-operated door operated by a tension cable, being mountable onto the cable-operated door and configured for cooperating with the tension cable so as to immobilize the cable-operated door with respect to the fixed structure by a braking arm in the event of a loss of tension in the cable. The brake device is provided with an anti-theft mechanism including a catcher assembly and a protrusion operatively projecting from the braking arm. The catcher assembly is operatively connectable to the fixed structure and the protrusion is shaped, positioned and sized with respect to the catcher assembly so as to be engaged with the catcher assembly when the braking arm is operated into the engaged configuration caused by a given loss of tension in the cable, thereby preventing the cable-operated door from being displaced upwardly along the fixed structure as a result of the catcher assembly abutting against the protrusion of the braking arm.
Abstract:
In a window regulator 10, when a pin bolt 42 provisionally attached to a pulley 22 and a pulley support 54 is fastened to a door panel 14 by a nut 52, the pulley 22 and the pulley support 54 are supported on the pin bolt 42 and attached to a predetermined position on the door panel 14. Here, in the above-described provisionally attached state, the pin bolt 42 is held in the pulley 22 by pin member holding claws 74 of the pulley 22, and the pulley 22 is held in the pulley support 54 by pulley holding claws 68 of the pulley support 54. Consequently, when the pin bolt 42 is to be fastened to a body panel, the pulley 22, the pulley support 54, and the pin bolt 42 can be handled as a single part. Thus, the work of attaching a pulley and a pulley support to a body panel of a vehicle can be facilitated.
Abstract:
A vehicle door drive unit for raising and lowering a glass plate is constructed so that a plurality of pulleys across which wires extend are provided at upper and lower sides of a base panel. The glass plate is supported by a carrier plate which is connected to the wire ends. The glass plate is moved up and down by the wires and is prevented from excessively moving in a vehicle inward direction when the door is closed by a supporting rod positioned along an upward and downward path of the glass plate and a contact member. Trumpet shaped guide portions are formed at the edges of holes of the wire fixing portions of the carrier plate and the circumferential surfaces of a V-shaped tensioner are provided for eliminating slack in the wires.
Abstract:
A cable tensioner includes two cams mounted to face each other that pivot about a common spindle. A torsion spring is centered on the spindle. The torsion spring includes a first end in abutment with a first cam and a second end in abutment with a second cam. The torsion spring applies a torque onto each of the cams to reduce an angular distance between the cams when a cable exhibits insufficient tension. The cable tensioner is placed in a window regulator mechanism to simultaneously tension a lower cable and an upper cable of the device. Furthermore, the tension of one cable through the cable tensioner is reversible since the tension of each cable is balanced with the tension of the other cable.
Abstract:
An automotive vehicle door has a glass window that is raised and lowered by a window regulator that includes a roller cable assembly (15). The roller cable assembly (15) has a rolled section guide rail (18) and a bracket assembly (16) at the lower end portion of the glass window that runs on an L-shaped flange (36) of the guide rail (18). The roller cable assembly (15) includes upper and lower roller assemblies (28 and 30) at the respective upper and lower ends of guide rail (18) and a cable (20) that is trained on rollers (22 and 24) of the roller assemblies and on a drive roller (26) that is driven by an electric motor (32). Each roller assembly includes a base (42) that is slideably attached to the guide rail (16) and a detachable cap pin (44) that attaches the guide roller to the base (42).
Abstract:
A motor vehicle door module, built as a preassembled unit, includes a windowpane movable between open and closed positions, an integrated window regulator assembly including a drive mechanism such as a drive motor or hand crank for moving the windowpane between the open and closed positions, a cable assembly, cable routers such as pulleys or sliders, a seal assembly, and a door frame assembly including run channels. The windowpane includes a bracket assembly which is slidably disposed within the run channels. The cable assembly includes a cable connected to the bracket assembly and the drive mechanism for transferring a force of the drive mechanism to the bracket assembly to move the windowpane between the open and closed positions. The cable routers are attached to fore and aft door frames of the door frame assembly and route the cable between the drive mechanism and the bracket assembly. The seal assembly forms a seal between the windowpane and the door frames and between the windowpane and the motor vehicle body. The windowpane may be positioned so that in the closed position, the windowpane is generally flush with an exterior surface of the motor vehicle body. The brackets of the bracket assembly and the run channels may be T, U, J and I shaped in cross section. The cable can be attached to the bracket assembly by a snap fit carrier.
Abstract:
A thin window regulator which can be assembled easily and which requires less installation space inside a door panel is disclosed. Both longitudinal ends of a belt are connected to a pair of sliders and the belt is made into a ring shape. Sliders are movable along a guide rail and are biased closer to each other by springs. Thus, since the ring-shaped belt is wound around a sprocket and the sliding portion, tension is not reduced by a creep phenomenon and the belt does not loosen. One end of the ring shaped belt is formed to be wound around the sliding portion. Thus, the window regulator can be made thinner compared with prior art systems in which both ends of a belt are wound around pulleys and a required installation space inside the door at the upper portion of the guide rail can be made thinner.
Abstract:
A window regulator comprising a vertically extending support member having respectively on upper and lower ends thereof turn up guide members, a drive cable extending between the two turn up guide members and being connected to a movable driven member such as a bracket connected to a window glass, and a drive mechanism for moving the drive cable. One of the turn up guide members is movably supported on the support member such that the distance between the turn up guide members can be changed, and a spring is provided to urge the movable turn up guide member in the direction separating from the stationary turn up guide member.
Abstract:
An operating mechanism for the window in a motorcar door and the like includes guiding devices, including at least one deflecting element, which engage a wire, cable or other elongated tension member and guide the tension member on the door in a loop-shaped path when the tension member is driven in the path alternatively in two opposite, longitudinal directions. The motion of the tension member is transmitted to the window. The tension member stretches under the longitudinal stresses exerted thereon by the drive and the window and needs to be tensioned. According to the invention, a spring in a permanently stressed condition biases the deflecting element in a direction to lengthen the path of the tension member and for thereby compensating for slack in the engaged portion of the tension member when the tension member moves in one longitudinal direction, whereby the spring reaches a partly relaxed condition. A protecting mechanism protects the spring against return from the partly relaxed condition toward the stressed condition when the tension member moves in the opposite direction.
Abstract:
The window operating mechanism in a motorcar door includes a window support moved by a bowden cable extending in an angular loop. The wire of the cable is protected in the corners of the loop by a flexible sheath deflected into an arc by a rigid U-channel having an open convex side and held in the groove of the channel by annular end pieces. An adjacent straight portion of the wire is fastened to the window support in a slot of a tubular guide having one end received in a blind groove of one of the end pieces.
