Abstract:
A door control system includes a door check assembly, a hinge assembly, and a controller. The door check assembly includes a housing having a cylinder, a piston and magnetorheological fluid disposed within the cylinder, and a fluid passageway disposed within the housing. The fluid passageway receives the fluid therein for facilitating reciprocating movement of the piston within the cylinder. The door check assembly also includes a magnetic flux generator configured for generating magnetic flux within the fluid passageway. The hinge assembly is coupled to the piston, and is configured for attachment to a door. The controller includes a sensor configured for attachment to the door, and magnetic flux controller coupled to the flux generator. The magnetic flux controller is configured to effect changes in the magnetic flux and is in communication with the position sensor for controlling movement of the door in accordance with sensor data of the door received from the position sensor.
Abstract:
An integrally moulded object body is disclosed for retaining fasteners in a pre-attachment position and deforming to accommodate attachment tolerances. The object body has a fastener retaining portion that has an aperture defined therein that has a fastener-engaging edge that grips the shaft of the fastener in the pre-attachment position. The fastener retaining is deformable to allow the fastener to move laterally and be attached off-center from the pre-attachment position to accommodate attachment tolerances. The fastener retaining portion can have areas of weakness to allow deformation. These areas of weakness can comprise areas of reduced thickness or radial extensions that extend towards the perimeter of the fastener retaining portion. The object body also has a clearance portion that defines a mounting face that the fastener does not extend past in the pre-attachment position. The object body can further comprise a compression portion that engages with the shoulder of the fastener and is compressed between the shoulder the object that the object body is attached onto in the attachment position. The compression portion can also have a bushing that provides increased torque retention by engaging with the fastener shoulder and the object that the object body is attached onto.
Abstract:
A window regulator assembly having cables for driving one or more lifter plates along rails includes connectors for connecting the ends of cables together. The connectors are connectable together in a 'use' position and can be held in a lifter plate in the use position. By having the connectors connect to each other they withstand the tension in the cables when the window regulator assembly is at rest and the lifter plate is only required to withstand the differential tension between first and second cable segments during movement of the lifter plate. This allows the lifter plate to be formed from a relatively lower strength and less expensive material since it is subject to relatively lower stresses than prior art lifter plates.
