Extendable exterior rearview mirror assembly
First Claim
1. An electrically extendable exterior rearview mirror assembly comprising:
- a mirror subassembly having a housing and a reflective element supported in said housing;
a bracket adapted for mounting to a vehicle;
a support mounting said mirror subassembly to said bracket, said support extending into said housing, said mirror subassembly being movable along said support and having a retracted position and at least one outboard position for said mirror subassembly and defining a direction of extension; and
a drive assembly supported in said housing and drivingly coupled to said support, said drive assembly including a drive screw and a motor driving said drive screw, said drive screw extending into said support and drivingly engaging an inner surface of said support, said inner surface includes a plurality of threads, said drive screw engaging said threads to thereby move said housing along said support, said drive assembly selectively moving said mirror subassembly along said support, said drive screw including a compressible end portion having a plurality of drive screw threads for engaging said threads of said support, and said compressible portion compressing and disengaging said from said threads of said support when a force is applied to said housing in said direction of extension defining a clutch mechanism.

Abstract
An extendable exterior rearview mirror assembly includes a mirror subassembly, a bracket which is adapted for mounting to a vehicle, and a support which mounts the mirror subassembly to the bracket. Support extends into the housing which is movable along the support. The housing includes a retracted position and at lease one outboard position, which define a direction of extension. The mirror assembly further includes a drive assembly which is supported in the housing and drivingly coupled to the support. The drive assembly selectively moves the housing along the support. The mirror assembly further includes a clutch mechanism which drivingly decouples the drive assembly from the support when a force of sufficient magnitude is applied to the housing in the direction of extension such that the housing can be manually moved along the support.
