US Patent:

48938653, Jan 16, 1990

Filed:

Aug 11, 1988

Appl. No.:

7/230942

Inventors:

Michael J. McClain - Dayton OH
Harry C. Buchanan - Spring Valley OH
Glenn R. Reed - Dayton OH

Assignee:

General Motors Corporation - Detroit MI

International Classification:

B62D 2508

US Classification:

296192

Abstract:

A unitized cowl and wiper arm assembly includes a blow molded plastic shell structure and two wiper arms of the integral type. At two locations, the shell is reformed so as to create an area of increased stiffness that includes a pair of spaced, overhanging interior flanges. This allows the journal portion of the arms to pass through the shell and be pivoted thereto between the spaced interior flanges. Thereafter, the arm is rigidly and securely supported. The leakproof interior of the shell may also be used for a fluid reservoir.

International Classification:

F16F 904

US Classification:

267 6421

Abstract:

An air spring damper used in a vehicle suspension system with upper, intermediate and lower chambers and incorporating a reservoir tube which has an anti-friction rod guide and bearing assembly therein which lubricates the hollow rod of a piston as it strokes in their reservoir tube in jounce and rebound. An elastomeric air sleeve is featured which is connected to a top mount fastened to the vehicle body. An elastomeric isolator of this mount pivotally connects the piston rod to the body while sealing the upper end of the air sleeve. The air sleeve is supported full time by an outer elastomeric sleeve for improved air sleeve operation. A jounce bumper mounted internal of the reservoir tube is compressible to resist and cushion jounce strokes of the piston. This damper provides optimized vehicle body isolation and damping of both body and wheel axle at their natural frequencies.

International Classification:

B60S 144
B60S 140

US Classification:

1525023

Abstract:

A wiper blade support is joined to a wiper arm by a yielding mechanism that maintains the two in a fixed angular relation during normal wipe, but which yields to allow the wiper blade to move more closely parallel to the windshield lower edge at park. The yielding mechanism includes a leaf spring indirectly joined between the wiper arm and blade support which buckles only when the wiper blade hits the lower edge of the windshield, allowing the compensating blade rotation, but remains flat during normal wipe.

International Classification:

US Classification:

1525016

Abstract:

A windshield wiper system for automotive vehicles includes a mechanism for causing a wiper blade assembly to swing, relative to the wiper arm, between an extended position of the wiper blade assembly and a retracted position of the wiper blade assembly. More specifically, the mechanism causes a link, which is attached to the wiper blade assembly, to swing as the wiper arm moves into and out of the hidden park position. A first embodiment includes a "four-bar linkage" which transfers to oscillatory movement of a drive arm of a wiper system to pivotal movement of the link over a limited range of motion of the drive arm corresponding to movement of the wiper blade assembly into and out of the hidden park position. A second embodiment includes a cam element which selectively engages a fixed pin over a range of motion of the drive arm corresponding to movement of the wiper blade assembly into and out of the hidden park position.

US Classification:

417380

Abstract:

This disclosure relates to a vacuum pump assembly which is adapted to be operated by the pulsating exhaust gases of an internal combustion engine. The pump assembly includes a reciprocable pump means and an actuating means including a reciprocable actuating member in communication with the exhaust gases and drivingly connected to the pump means to reciprocate the same. The actuating means includes a first housing member and a second spring steel housing member which together with the reciprocable actuating member define an air spring for effecting movement of the actuating member through one of its strokes and which together serve to position and biasingly retain the pump means in assembled relation with the actuating means.

Abstract:

A windshield wiper system for automotive vehicles includes a power source and a driver for causing a wiper blade assembly to swing, relative to the wiper arm, between an extended position of the wiper blade assembly and a retracted position of the wiper blade assembly. The power source and driver, which are selectively connected to one another, cause a link, which is attached to the wiper blade assembly, to swing as the wiper arm moves into and out of the hidden park position. A first embodiment uses a pressure fluid source as the power source and a piston as the driver to cause pivotal movement of the link as the wiper blade assembly moves into and out of the hidden park position. A second embodiment uses an electrical source as the power source and an electrical motor as the driver to cause pivotal movement of the link as the wiper blade assembly moves into and out of the hidden park position.
