Abstract
Abstract A modularly constructed motor vehicle control stalk 10 comprises a handle base 20 that engages any of a plurality of vehicle steering column switch actuator assemblies 14. The base 20 accommodates an interchangeable trim sleeve 48 for styling the control stalk 10 to be cosmetically compatible with any of a variety of vehicle interiors. The trim sleeve 48 is secured to the base 20 and supported by a standardized stalk handle 56 which also acts as a receptacle for a switch knob 84 for actuating any of a variety of vehicle operator functions. The switch knob includes interiorly mounted contacts which engage contact surfaces of a printed circuit board when the switch knob is compressed or rotated.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
207 words
A method of constructing a modular vehicle control stalk comprising the steps of: (a) selecting a handle base capable of being secured to a column switch assembly suitable for installation in a steering column of a plurality of vehicle models; (b) choosing a hollow trim sleeve for styling said vehicle control stalk for compatibility with a vehicle interior of any one of a plurality of vehicle models; (c) positioning a stalk handle into said trim sleeve so that a portion of said stalk handle engages said trim sleeve supportively; (d) attaching said stalk handle and supportively engaged trim sleeve onto said handle base by fitting said stalk handle slidably into said handle base and fitting said trim sleeve circumferentially about said handle base; and (e) securing said stalk handle to said handle base, using a mechanical means for preventing withdrawal of said slidably fitted stalk handle from said handle base, whereby said modularly constructed vehicle control stalk comprises, said stalk handle and supportively engaged trim sleeve being attached to said handle base by said stalk handle being slidably fitted into said handle base, said trim sleeve being circumferentially fitted about said handle base and said mechanical means securing said stalk handle from withdrawal from said handle base.
Claim 2
Independent Claim
207 words
A method of constructing a modular vehicle control stalk comprising the steps of: (a) selecting a handle base capable of being secured to a column switch assembly suitable for installation in a steering column of a plurality of vehicle models; (b) choosing a hollow trim sleeve for styling said vehicle control stalk for compatibility with a vehicle interior of any one of a plurality of vehicle models; (c) positioning a stalk handle into said trim sleeve so that a portion of said stalk handle engages said trim sleeve supportively; (d) attaching said stalk handle and supportively engaged trim sleeve onto said handle base by fitting said stalk handle slidably into said handle base and fitting said trim sleeve circumferentially about said handle base; and (e) securing said stalk handle to said handle base, using a mechanical means for preventing withdrawal of said slidably fitted stalk handle from said handle base, whereby said modularly constructed vehicle control stalk comprises, said stalk handle and supportively engaged trim sleeve being attached to said handle base by said stalk handle being slidably fitted into said handle base, said trim sleeve being circumferentially fitted about said handle base and said mechanical means securing said stalk handle from withdrawal from said handle base.
