Patent number: 8777316Abstract: A vehicle seat is movable between a first position and a second position and includes a scat back and seat cushion for coupling to a track adjuster for use in a vehicle. The vehicle seat includes a recliner mechanism coupled to the seat back and the seat cushion. The vehicle seat further includes a stow mechanism coupled to the recliner mechanism and an easy entry mechanism coupled to the recliner mechanism and stow mechanism, wherein, when the stow mechanism is actuated, the easy entry mechanism is not actuated and when the easy entry mechanism is actuated, the stow mechanism is not actuated.Type: GrantFiled: August 2, 2007Date of Patent: July 15, 2014Assignee: Johnson Controls Technology CompanyInventors: Tamizharasan Shanmugam, Kurt Siebold, Paul Arthur Gilmore, David D. Sheill, Bruce A. Hiemstra

Patent number: 4781272Abstract: The invention relates to a friction pad for a disc brake and a disc brake assembly in which the friction pads are slidably supported by tabs extending radially outward of the friction pad backing plates on spaced axially extending, stepped edges of an aperture provided to the disc brake caliper. The friction pad tabs include support surfaces or shoulders which are non-symmetrical and permit the tabs to be assembled only when properly oriented.Type: GrantFiled: July 8, 1985Date of Patent: November 1, 1988Assignee: Rockwell International CorporationInventors: David D. Sheill, Donald J. Davidson, David J. Dettloff

Patent number: 4548300Abstract: In a vehicle disc brake, a friction pad having a radially outer portion supported by a slidably mounted caliper is stabilized by engaging a radially inner portion of the friction pad backing plate with an adjacent depending leg of the caliper.Type: GrantFiled: August 31, 1983Date of Patent: October 22, 1985Assignee: Rockwell International CorporationInventors: David D. Sheill, Donald J. Davidson, David J. Dettloff

Patent number: 4516666Abstract: An anti-rattle clip is comprised of a length of spring wire formed to provide two spaced clip legs joined by an intermediate segment. Each clip leg is formed adjacent the intermediate segment to abut spaced areas of the radially outer edge of a friction pad backing plate and the ends of the clip legs are formed to abut spaced areas of the radially outer edge of the other friction pad backing plate. Segments of the clip legs between the segments abutting the friction pad backing plates are formed to extend radially inward and under the circumferentially spaced edges of an aperture provided to the disc brake caliper bridge.Type: GrantFiled: June 25, 1984Date of Patent: May 14, 1985Assignee: Rockwell International CorporationInventor: David D. Sheill

Patent number: 4503946Abstract: An improved braking piston for a disc brake is of the type which includes a disc mounted for rotation about an axle and a brake housing mounted on the axle in alignment with a friction surface of the disc. The braking piston has an interior end at least partially mounted within the housing and an external end outwardly of the housing adjacent the friction surface of the disc. A powershaft is mounted within the housing in coaxial alignment with the braking piston and is capable of selective rotation by an air disc brake actuator mounted on the housing. The powershaft has worm gear teeth engaged with mating teeth on the interior end of the braking piston.Type: GrantFiled: August 31, 1983Date of Patent: March 12, 1985Assignee: Rockwell International CorporationInventors: Donald J. Davidson, David D. Sheill

Patent number: 4503595Abstract: A method is provided for forming a braking piston for a disc brake of the type which includes a disc mounted for rotation about an axle. A brake housing is mounted on the axle in alignment with a friction surface of the disc. The piston has an interior end at least partially mounted within the housing and an external end outwardly of the housing adjacent the friction surface of the disc for axial movement toward and away from the disc. A flexible boot is secured to the housing and has an end extending into a circumferential channel around the piston. The housing has a plurality of first axially extending splines around an interior cylindrical surface thereof. The method includes the steps of providing the piston with an interior end having a cylindrical outer surface and forming a cylindrical groove thereabout.Type: GrantFiled: August 31, 1983Date of Patent: March 12, 1985Assignee: Rockwell International CorporationInventor: David D. Sheill

Patent number: 4502572Abstract: An improved disc brake is of the type which includes a disc mounted for rotation about an axle. An axle housing is mounted on the axle in alignment with a friction surface of the disc. An axially movable braking piston has an interior end at least partially mounted within the housing and an external end outwardly of the housing adjacent the friction surface of the disc. The braking piston has a plurality of axially extending splines about an exterior surface of the interior end to mate with corresponding splines on an interior surface of the housing to limit rotation of the braking piston relative to the housing. The brake is actuated by the piston being axially moved toward and away from the friction surface of the disc. Lubricant can be supplied and periodically resupplied to an interior of the housing. The improvement includes providing the housing with a cylindrical recess at the end thereof adjacent the disc for receipt of a sealing ring made of resiliently compressible material.Type: GrantFiled: August 31, 1983Date of Patent: March 5, 1985Assignee: Rockwell International CorporationInventors: Donald J. Davidson, David D. Sheill

Patent number: 4478317Abstract: A slack adjuster is for a disc brake of the type which includes a disc mounted for rotation about an axle and a caliper brake having a housing mounted on the axle in alignment with a friction surface of the disc. A braking piston is mounted in the housing for axial movement toward and away from the friction surface of the disc. Brake actuation produces rotating movement of a powershaft mounted in the housing which will in turn produce a corresponding axial movement of the braking piston through a non-rotating powershaft nut. An adjusting sleeve is between the piston and the powershaft nut and is threadably coupled to the piston and capable of rotation relative thereto to adjust the axial position of the piston. The adjusting sleeve is capable of rotating in a direction which will cause the piston to be adjusted toward the disc and is prevented from rotating in the opposite direction by a one-way clutch element between the adjusting sleeve and the housing.Type: GrantFiled: April 11, 1983Date of Patent: October 23, 1984Assignee: Rockwell International CorporationInventor: David D. Sheill

Patent number: 4406352Abstract: A fluid motor moves a lever to turn a power screw mounted for rotation by a pair of axially spaced bushings. External threads on the power screw engage internal threads on an actuator and slide or translate the actuator and a piston in a brake-applying direction. A spring moves the piston in the opposite direction to a rest position. A cap fits over a medial flange of the power screw and has a spline connection with the actuator to prevent rotation of the actuator. Four bolts connect the fluid motor mounting bracket and the cap to a caliper which slides on parallel pins fixed to a torque plate secured to a vehicle axle.Type: GrantFiled: December 1, 1980Date of Patent: September 27, 1983Assignee: Rockwell International CorporationInventors: James P. Scott, Charles H. Lantz, David D. Sheill
