Abstract
A safety system for a motor vehicle having an automatic transmission, a shift lever movable into select positions for allowing the transmission to assume the corresponding gear conditions thereof, stepped operation surfaces, and a stop pin movable with the shift lever and slidably engageable with the stepped operation surfaces for retaining the shift lever at one of the select positions. A position detector switch is provided which connects the starter motor of the vehicle with an electric power source. The position detector switch includes at least one stationary contact member mounted to one of the stepped operation surfaces, and a single movable contact member mounted to the stop pin at the portion engageable with the stepped operation surfaces.
Claims7
In a motor vehicle having a starter motor, an electric power source, an automatic transmission, a shift lever movable into select positions for placing the transmission in corresponding gear conditions, means defining stepped operation surfaces, and a stop pin carried on said shift lever to move therewith and slidably engageable with said stepped operation surfaces for retaining said shift lever at ones of said select positions,
- a safety system comprising:
- (a) a starter switch interposed between said starter motor and said electric power source, and
- (b) a position detector switch connected in series with said starter switch for energizing said starter motor upon closure of said starter switch and said position detector switch, said position detector switch including at least one stationary contact member mounted to at least a part of one of said stepped operation surfaces, and a single movable contact member mounted to said stop pin at the portion engageable with said stepped operation surfaces whereby engagement of said stop pin with said at least one stationary contact member of said one stepped operation surface both retains said shift lever and closes an electrical circuit for energizing said starter motor.
