Motion translation mechanism for a vehicle seat switch
First Claim
1. In a motion translation mechanism which is selectively responsive to the presence and absence of a downward vertical force, said mechanism comprising:
- a switch assembly having a plunger which is movable laterally between extended and retracted positions for electrically closing an opening said switch assembly;
a leaf spring having a first end portion, a second end portion, and an upwardly convexed central portion, said first end portion being connected to said second end portion by said upwardly convexed central portion, said upwardly convexed central portion being vertically movable in response to the movement of the vertical force;
a mounting bracket having first and second stop means for engaging said respective first and second end portions of said leaf spring;
a coil spring for resiliently biasing said first end portion of said leaf spring against said first stop means; and
said second end portion of said leaf spring being operatively connected between said second stop means and said plunger for moving laterally said plunger to the retracted position in response to the downward movement of said upwardly convexed central portion so as to electrically close or open said switch assembly.

Abstract
A motion translation mechanism is adapted for use in a vehicle seat-operated switch and is selectively responsive to the presence or absence of a downward vertical force. The motion translation mechanism includes a switch assembly having a plunger, a leaf spring, and coil spring. The coil spring is used to resiliently bias a first end portion of the leaf spring against a first stop. The second end portion of the leaf spring is operatively connected between a second stop and the plunger for moving laterally the plunger to a retracted position in response to the downward movement of an upwardly convexed central portion of the leaf spring so as to electrically actuate the switch assembly.

13. In a motion translation mechanism which is selectively responsive to the presence and absence of a downward vertical force, said mechanism comprising:
-
a mounting bracket having a first end compartment, a central compartment, and a second end compartment; a switch assembly mounted in said second end compartment and having a plunger which is movable laterally between extended and retracted positions for electrically closing and opening said switch assembly; a leaf spring mounted in said central compartment and having a first end portion, a second end portion, and an upwardly convexed central portion, said first end portion being connected to said second end portion by said upwardly convexed central portion, said upwardly convexed central portion being vertically movable in response to the movement of the vertical force; said mounting bracket having first and second stop means for engaging said respective first and second end portions of said leaf spring; a coil spring mounted in said first end compartment for resiliently biasing said first end portion of said leaf spring against said first stop means; said second end portion of said leaf spring being operatively connected between said second stop means and said plunger for moving laterally said plunger to the retracted position in response to the downward movement of said upwardly convexed central portion so as to electrically close or open said switch assembly; and a mounting plate being joined to said mounting bracket for housing said switch assembly, leaf spring, and coil spring therebetween. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
