Abstract:
A plastic vehicle body attachment system for a motor vehicle. The attachment system includes a metal support, a plastic panel having an aperture, and a fastener. The fastener is disposed in the aperture and detachably couples the plastic panel to the metal support. The fastener is smaller than the aperture by an amount that varies in relation to the distance between the fastener and a fixed point on the composite panel such that the size of the aperture increases as the distance between the fastener and the fixed point increases.
Abstract:
An overcenter latch assembly for securing a moveable member including a bracket secured to a first member and a saddle secured to a second member in opposed relation to the bracket. The saddle includes longitudinally spaced apart, transversely extending recesses formed thereon. Each recess is formed with a transversely extending raceway ending in opposed inboard and outboard pivot sockets. A release cover is pivotally connected to the bracket. The release cover has a member pivotally secured thereon. The pivoting member has opposed extensions adapted to be received in the inboard pivot socket of the recess for pivotal movement of the release cover about an inboard axis in a latching direction from an initial unlatched position. The raceways are oriented in the direction substantially perpendicular to a longitudinal axis of the release cover with the release cover in an unlatched to latched position such that initially rotating the release cover in a latching direction pivots the release cover about the inboard axis through a predetermined first angle so as to cause downward force on the saddle via the extensions such that continued rotation causes the extensions to travel to an outboard position on the raceways and to seat in associated outboard sockets. Continued rotation of the release handle about an outboard axis to the latch position causes the release cover to travel to a predetermined locked position. The locked position has an overcentered length resulting in reduced effort to latch the assembly.
Abstract:
A vehicle seat mounting mechanism including oppositely disposed pairs of parallel links between a base and a seat carrier, and a first air bag spring operatively connected between the base and the links for absorbing vertical-upward motion induced by road shocks, and a second air bag spring secured between the base and the seat carrier for absorbing vertical-downward motion induced by road shocks. A separate shock absorber mounted between the base and the seat carrier serves to dampen the springing action of the first and second air bag springs.
Abstract:
A ventilation system for a lightweight automobile having a plastic body includes a heating air inlet in fluid communication with fresh air at the engine hood upper cowl of the automobile. The air inlet is rigid plastic and is bonded to the hood to stiffen the hood. The fresh air is directed through the inlet to a heat exchanger shroud within the engine compartment, and the engine exhaust pipe passes through the shroud to heat the air in the shroud. From the shroud, the heated fresh air passes through a bulkhead valve into the passenger compartment, where it can be directed toward the passengers' feet or against the windshield to defrost the windshield. In addition, a rigid plastic fresh air plenum is transversely mounted in the passenger compartment as an instrument panel, and the fresh air plenum stiffens the body. Fresh air from the cowl is directed into the plenum and out of selectively coverable openings in the plenum to cool the passenger compartment.
Abstract:
A tailgate is hinged to a passenger van type vehicle body above a substantially vertical rear access opening for swinging movement about a horizontal hinge axis. The tailgate is counterbalanced through its range of movement by spring devices and is opened and closed by a powered actuator mounted on a rear vehicle body pillar. The actuator includes a reversible electric motor driving a worm shaft that drives a worm gear to pivot a crankarm about an axis parallel to the hinge axis. A roller mounted on the crankarm is received in a guide channel that is fixed to the tailgate and extends at right angles to the hinge axis with the pivoting movement of the crankarm thereby translated into swinging tailgate opening and closing movement. The motor is connected with torque sensing circuitry that detects an excessive motor torque demand when the tailgate encounters an obstacle and stops the motor. A normally engaged clutch maintains drive connection between the worm gear and the crankarm to effect normal tailgate opening and closing by the motor and slips to allow manually applied force on the tailgate to open and close same when the motor is not operating.

A first actuator sub-assembly is operatively connected between the reversible motor and the wiper pivot assembly for reciprocally actuating the wiper blade. A second actuator sub-assembly is operatively connected between the reversible motor and the windshield wiper blade for telescopically moving the wiper blade.
Abstract:
A vehicle door assembly including front and rear doors which are latched together, and wherein the usual center pillar is integral with the front door. The rear door can be unlatched from the front door and the rear pillar and opened independent of the front door. Rollers on the rear door slide in a bottom track to roll the door along side the rear of the vehicle.
Abstract:
A seat tilt mechanism includes a seat frame pivotally secured at its forward end to a floor mounted support. A first toggle link is pivotally secured at a pivot axis eccentrically displaced from the tilt axis for the seat and is in turn pivotally secured to a second link whose other end is pivotally secured to the rear of the seat frame about a support axis. An actuator is pivotally secured for rotation about the support axis together with the second link and preferably, the second toggle link is formed as a portion of the actuator. Moreover, the actuator forms a support leg for supporting the rear end of the seat in the seating position. A latch mechanism retains the seat in its seating position. The latch mechanism is supported by a latch housing which rotates in unison with the support leg so that both members are retracted beneath the seat as the seat is pivoted from its seating position to an access position which permits access to an area behind the seat. Preferably, the seat is retained in its access position by an over-center toggle relationship between the first and second toggle links.
Abstract:
An axle beam for supporting drivetrain and steering components of a motor vehicle comprises a first elongated channel member having a substantially hat-shaped cross section including first and second sidewalls, a bottom wall having a longitudinal edge at one edge of each of the sidewalls, and side flanges extending outwardly from the other edges of the sidewalls. A second elongated member includes surface portions registering with and bonded to the side flanges of the first member. An end plate is secured at each longitudinal end of the beam and is configured to support a wheel spindle support knuckle. Additional steering structure including the steering control assembly can be mounted on sidewalls of the beam. Additional reinforcement can be provided to the axle beam by corrugated web panels inserted within the longitudinal channel as well as by flanged apertures formed in the sidewalls of the first elongated member. Preferably, the first and second elongated members are stamped to conveniently form corresponding configurations which further serve to reinforce the axle beam and provide clearance for adjacent vehicle components.
Abstract:
A lift type tailgate on a passenger van type vehicle body is operated by an electric motor powered actuator with an electronic control circuit utilizing a microprocessor operating under program control to respond to user-initiated opening and closing signals to move the tailgate in the selected direction. In the control circuit, feedback information to the microprocessor indicative of tailgate position is provided by a potentiometer coupled with the actuator motor and the microprocessor is programmed to operate with this information to stop the tailgate at a wide open position, a partially closed position and a fully closed position. Obstruction detection is performed by the microprocessor using an obstruction detection circuit and additionally by monitoring the position signal input from the potentiometer to stop the tailgate on encountering an obstacle. Activation of a tailgate latching mechanism is performed under the control of the microprocessor using a solenoid drive circuit and warning or alerting sounds indicating tailgate closure operation including tailgate stoppage at the partially closed position are provided in accordance with audio data received from the microprocessor.
