Abstract:
A rail assembly which is especially advantageous for use in constructing the frame and underbody of a motor vehicle comprises an upper channel member, a lower channel member and an intermediate member or web in the form of a corrugated sheet secured between the channel members and whose margins abuttingly engage the peripheral walls of the channels. Each furrow and ridge preferably comprises a planar panel portion. Each planar panel portion is interconnected by a web panel portion which is preferably angled at an acute angle with respect to the transverse axis perpendicular to the longitudinal axis of the rail. Preferably, each planar panel portion has a trapezoidal shape to maximize resistance to bending moments along the longitudinal axis of the rail. The rail design can also be incorporated into other structural elements in a vehicle, i.e. in a pillar arch or a vehicle body, to provide additional rigidity to the vehicle structure. In the preferred embodiment of the present invention, a pair of assembled frame rails are sandwiched between upper and lower flooring panels configured to form hollow transverse and longitudinal beams. In addition, the hollow beams formed by the flooring panels support a pillar arch and a cowl structure which are interconnected by a cross bar.
Abstract:
A vehicle air deflector of the disclosure includes an air scoop mounted by an adjustable connection on a support portion of a support member that also has a mounting portion which is positioned between an associated vehicle side door and a detachable exterior rear view mirror support of the door. The adjustable connection for mounting the air scoop is preferably of the ball and socket type so as to permit adjustment of the horizontal and vertical directions of air deflection independently of each other. As disclosed, the rear view mirror and air deflector are located adjacent a front inclined edge of the side door window. The air scoop of the deflector has a curved shape and is positionable in a streamlined position so as to be concave in a downwardly and inwardly facing direction. In this streamlined position, a curved forward and upper edge and a curved rear edge cooperate to give the air scoop a swept-back shape. A straight lower edge of the air scoop is supported by an integral elongated bracket of a first ball socket portion that is cooperable with a second ball socket portion to receive a ball on the support portion of the support member. The mounting portion of the support member has a plate-like construction and defines an opening that receives rear view mirror remote controls upon being positioned between the door and the rear view mirror support. At least one hole in the mounting portion on one side of the opening and an elongated slot on the other side thereof receive securement screws of the rear view mirror support during mounting of the air deflector. The opening for the mirror controls opens in a downward direction below an upwardly extending projection that also defines a hole for receiving an additional securement screw.
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:
An independent suspension system for a vehicle driving axle is disclosed which includes a leading lower control arm which pivots about an axis which is nearly perpendicular to the upper control arm pivot axis and which is nearly perpendicular to the vehicle center line. By providing this perpendicular relationship between the pivot axes of the upper and lower control arms, an imaginary steering point results. This new imaginary steering point allows for improved vertical wheel travel, while minimizing the distance of half shaft plunge. By improving the vertical wheel travel and minimizing the distance of half shaft plunge, the ride of the vehicle is improved.
