Abstract
Abstract A window regulator for vehicles having a reversible motor provided with a sectional drive shaft, one section having a worm meshing with a worm gear which forms a part of a spring clutch. The clutch has a regulator pinion for connection to the usual gear sector of a window regulator. One section of the drive shaft is connected to the armature of the electric motor and the sections are connected by a torsion bar, rectangular in cross section and which extends freely through the shaft sections but extends into sockets at the outer ends of these sections, the sockets being rectangular in cross section.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
83 words
A vehicle window regulator comprising a rotary electric motor, output shaft from said motor, a worm on said shaft, thrust bearings for opposite ends of said shaft, adjustable means for effecting relative axial adjustment for said thrust bearings, a spring clutch having a driving member provided with a worm gear meshing with said worm, said spring clutch having a contractable and expansible coil spring, a driven member constituting part of the spring clutch, and a regulator pinion connected rigidly to said driven member.
Claim 2
Dependent Claim
83 words
A vehicle window regulator comprising a rotary electric motor, output shaft from said motor, a worm on said shaft, thrust bearings for opposite ends of said shaft, adjustable means for effecting relative axial adjustment for said thrust bearings, a spring clutch having a driving member provided with a worm gear meshing with said worm, said spring clutch having a contractable and expansible coil spring, a driven member constituting part of the spring clutch, and a regulator pinion connected rigidly to said driven member.
Claim 3
Dependent Claim
82 words
A vehicle window regulator as claimed in claim 1, in which a cup-shaped housing part encloses said spring clutch and worm and worm gear, a flat ring shaped cover for the open side of said housing part, said regulator pinion being disposed on the outer side of said cover, a gasket of elastomeric material sealing the space between the inner side of said pinion and the cover, and and annular blade on said gasket having wiping contact in rear of said pinion.
Claim 4
Dependent Claim
26 words
A vehicle window regulator as claimed in claim 1, characterized in that the angularity of the teeth of said worm is above the angle of friction.
Claim 5
Dependent Claim
39 words
A vehicle window regulator as claimed in claim 1, characterized by means to cause the armature of said electric motor to act as a dynamic brake for resisting reverse movement of said shaft upon stopping of the regulator movement.
Claim 6
Dependent Claim
101 words
A vehicle window regulator comprising a rotary electric motor, a pair of aligned independent hollow shaft sections one of which is connected to said motor, a torsion bar extending freely through said shaft sections and having its ends secured against rotation relative to the outer ends of said shaft sections, a worm on one shaft section, a spring clutch having a driving member provided with a worm gear meshing with said worm, said spring clutch having a contractable and expansible coil spring, a driven member constituting part of the spring clutch, and a regulator pinion connected rigidly to said driven member.
Claim 7
Dependent Claim
101 words
A vehicle window regulator comprising a rotary electric motor, a pair of aligned independent hollow shaft sections one of which is connected to said motor, a torsion bar extending freely through said shaft sections and having its ends secured against rotation relative to the outer ends of said shaft sections, a worm on one shaft section, a spring clutch having a driving member provided with a worm gear meshing with said worm, said spring clutch having a contractable and expansible coil spring, a driven member constituting part of the spring clutch, and a regulator pinion connected rigidly to said driven member.
Claim 8
Dependent Claim
48 words
A vehicle window regulator as claimed in claim 5, in which said torsion bar is rectangular in cross section, and the outer end portions of said shaft sections having bores of rectangular cross section for fitting the torsion bar affording axial movement therein but not relative rotational movement.
