Abstract

A cam-guided adjustable pedal actuator assembly for a vehicle includes a housing for connection to vehicle structure and a linear actuator operatively connected to the housing. The cam-guided adjustable pedal actuator assembly also includes a pedal operatively connected to the linear actuator for adjusting a position of the pedal relative to the housing. The pedal has a cam surface to cooperate with the housing as a force is applied to the pedal such that the housing and the pedal effectively act as one solid member to transfer force to an actuating member in a manner of a conventional pedal.

Claims

1. A cam-guided adjustable pedal actuator assembly for a vehicle comprising:

a housing adapted for connection to a vehicle structure;

a linear actuator operatively connected to said housing

a pedal connected to said linear actuator for adjusting a position of said pedal relative to said housing; and

said pedal having a cam surface to cooperate with a fixed portion of said housing as a force is applied to said pedal such that said housing and said pedal effectively act as one solid member adapted to transfer force to an actuating member.

2. A cam-guided adjustable pedal actuator assembly as set forth in claim 1 wherein said fixed portion of said housing comprises a roller connected to said housing to cooperate with said cam surface.

3. A cam-guided adjustable pedal actuator assembly as set forth in claim 2 including a retainer assembly for urging said cam surface toward said roller.

4. A cam-guided adjustable pedal actuator assembly as set forth in claim 1 wherein said pedal comprises an arm and a pad connected to a lower end of said arm.

5. A cam-guided adjustable pedal actuator assembly as set forth in claim 4 wherein said arm has an upper portion, said cam surface extending along said upper portion.

6. A cam-guided adjustable pedal actuator assembly for a vehicle comprising:

a housing adapted for connection to a vehicle structure;

a linear actuator operatively connected to said housing;

a pedal operatively connected to said linear actuator for adjusting a position of said pedal relative to said housing;

said pedal having a cam surface to cooperate with said housing as a force is applied to said pedal such that said housing and said pedal effectively act as one solid member adapted to transfer force to an actuating member;

a roller connected to said housing to cooperate with said cam surface;

a retainer assembly for urging said cam surface toward said roller; and

wherein said retainer assembly comprises said roller for contacting said pedal and a spring connected to said roller and said housing for urging said roller against said pedal.

7. A cam-guided adjustable pedal actuator assembly for a vehicle comprising:

a housing adapted for connection to a vehicle structure;

a linear actuator operatively connected to said housing;

a pedal operatively connected to said linear actuator for adjusting a position of said pedal relative to said housing;

said pedal having a cam surface to cooperate with said housing as a force is applied to said pedal such that said housing and said pedal effectively act as one solid member adapted to transfer force to an actuating member; and

wherein said linear actuator comprises a base operatively connected to said housing, a screw connected to said base and a nut connected to said pedal and engaging said screw for movement therealong.

8. A cam-guided adjustable pedal actuator assembly as set forth in claim 7 wherein said housing has a pair of opposed slots spaced laterally and extending longitudinally.

9. A cam-guided adjustable pedal actuator assembly as set forth in claim 8 wherein said nut includes at least one stud extending laterally and into said slots to prevent said nut from rotating and for movement therealong.

10. A cam-guided adjustable pedal actuator assembly as set forth in claim 9 wherein said slots are linear shaped.

11. A cam-guided adjustable pedal actuator assembly as set forth in claim 9 wherein said housing has a base wall and a pair of laterally spaced side walls extending from said base wall, one of said slots extending along one of said side walls.

12. A cam-guided adjustable pedal actuator assembly as set forth in claim 11 wherein said housing has a flange extending from said base wall adapted for connection to the actuating member.

13. A cam-guided adjustable pedal actuator assembly for a vehicle comprising:

a housing adapted for connection to a vehicle structure;

a linear actuator operatively connected to said housing;

a pedal connected to said linear actuator for adjusting a position of said pedal relative to said housing;

a fixed roller connected to said housing; and

said pedal having an arm and a pad connected to said arm, said arm having a cam surface to cooperate with said roller as a force is applied to said pedal such that said housing and said pedal effectively act as one solid member adapted to transfer force to an actuating member.

14. A cam-guided adjustable pedal actuator assembly as set forth in claim 13 including a retainer assembly for urging said cam surface toward said roller.

15. A cam-guided adjustable pedal actuator assembly for a vehicle comprising:
