A parking brake actuator for applying and releasing a cable-operated vehicle parking brake includes an operating lever pivotally mounted on a mounting bracket for movement between brake-released and a plurality of brake-applied positions. The operating lever is a unitary molding made of a glass-filled thermoplastic and has an integral footpad. A metal insert which mounts the cable end, includes a sector gear, that is secured to the operating lever by rivets and engages a pinion which is pivoted to the mounting bracket. The operating lever has a raised drive lug that is received in a mating drive aperture in the insert and transfers brake-apply forces from the operating lever to the sector. A one-way clutch normally permits the pinion to rotate freely when the operating lever is operated to apply the parking brake, but prevents reverse rotation of the pinion to maintain the parking brake applied. A clutch release is operable to disable the one-way clutch and permit reverse rotation of the pinion to release the parking brake and allow the operating lever to return to released position. The plastic operating lever only experiences the high brake-apply forces during brake-apply motion. When the parking brake is set, the operating lever is isolated from the cable load path.

Parking brake actuator with plastic operating lever

A mounting bracket assembly is disclosed for soft mounting a transmission shifter and simultaneously hard mounting a parking actuator to a vehicle floorboard. The bracket assembly comprises an elongated base plate having mounting holes for hard mounting the base plate longitudinally of the vehicle to the floorboard. The base plate has a pair of spaced rear upstanding flanges for mounting the parking brake actuator with its operating lever extending longitudinally of the vehicle. An elevated tower structure mounts the transmission shifter and includes depending legs which include four mounting pads. Cooperating mounting pads are formed on the base plate and interfit vertically with the leg mounting pads to locate the transmission shifter on the base plate with its operating lever extending beside the parking brake actuator operating lever. Rubber pads are interposed between the leg and base plate mounting pads and are bonded to these mounting pads to secure the tower structure to the base plate and simultaneously provide a soft mounting of the shifter to the vehicle floorboard.

Common shifter and parking brake mounting

An automatic transmission shifter for a vehicle comprises a unitary glass reinforced nylon housing open at the bottom and having interconnected, spaced upper, side and end walls. A slot is formed in the upper wall, a pair of spaced aligned apertured bosses are formed in the side walls, and integral flanges extend from the side and end walls and incorporate a plurality of spaced apertures for mounting the housing to vehicle structure. A pair of spaced, aligned position control plates, each comprising a plurality of notches, are formed interiorly on the side walls, a plurality of detent notches are formed interiorly on the housing on one of the side walls below the position control plates, and a shift cable access opening is formed in one of the end walls. A shift lever assembly including an operating lever extends upwardly through the slot. A plastic trunnion mounts the lever and a pivot pin carried by the boss apertures mounts the trunnion for pivotal movement of the lever among a plurality of transmission control positions. The ends of a position pin mounted centrally on the shift lever simultaneously engage notches in each position control plate to control lever movement between positions. A spring-biased detent ball mounted on the trunnion engages in the detent notches to locate the lever in each of the control positions.

Simplified automatic transmission shifter

A manual transmission shifter for operating a pair of transmission control cables includes a shift lever, a base, and a cross having first and second axles defining the first and second intersecting orthogonal axes. The first axle ends are pivotally mounted on the base for pivotal movement. A shift lever bracket mounts the shift lever and has a pair of spaced legs which are pivotally mounted on the second axle ends to enable relative pivotal movement of the shift lever about the second axis. A cable control member is attached at its lower end to one of the control cables and has a pair of spaced flanges at its upper end which are pivotally attached to the second axle outwardly of the shift lever bracket legs to enable pivotal movement of the cable control member about the second axis independent of pivotal movement of the shift lever. A bellcrank is pivotally mounted on the base on a third axis that is coplanar with the orthogonal axes. A control arm mounted on the shift lever bracket has a universal connection to a shoe slidably received in a slot in one leg of the bellcrank. This enables operation of the shift lever and cross about the second axis to operate the one cable without moving the other cable.

Manual transmission shifter

Apparatus is provided for operatively connecting an operating rod to a parking brake latch release lever when a vehicle instrument panel is installed to a vehicle support structure. A handle is mounted on one end of the operating rod that is pre-installed in the instrument panel prior to panel installation. The other end of the rod is provided with an elongated fitting having a series of spaced annular ridges comprising leading camming surfaces and trailing locking surfaces. The latch lever mounts a receptor fitting having an entry funnel that enters a central bore. A spring clip includes fingers which enter the bore through slots. The operating rod is initially pulled out to release position. When the instrument panel is later installed, the projector rod is guided into the receptor bore by the funnel. As the rod fitting is inserted, the spring fingers are cammed over the ridges by the camming surfaces until the rod fitting is fully inserted. The fingers engage the rod locking shoulder in that position to prevent withdrawal of the rod fitting. This operatively connects the operating rod to the release lever to enable parking brake release by manually pulling out the handle. The spring clip has a connecting portion extending outside of the receptor to enable grasping and removal to permit withdrawal of the rod fitting to enable instrument panel removal.
