Abstract

A vehicle occupant sensing system adapted for detecting a condition of a vehicle seat assembly including at least one emitter and at least one sensor disposed spaced relative to the emitter. The sensor is operable to detect relative distance between the emitter and the sensor to thereby detect the condition of the vehicle seat assembly. The vehicle occupant sensing system also includes at least one sensor assembly having a base and an upper slide member moveable toward and away from the base. The upper slide member includes at least one interference member that generates an interference fit between the emitter and the interference member to thereby securely mount the emitter to the upper slide member. The vehicle occupant sensing system may be employed in a vehicle seat to detect a condition of the vehicle seat.

Claims

1. A vehicle occupant sensing system adapted for detecting a condition of a vehicle seat assembly, said vehicle occupant sensing system comprising:

at least one emitter;

at least one sensor disposed spaced relative to said emitter and operable to detect relative distance between said emitter and said sensor to thereby detect the condition of the vehicle seat assembly; and

at least one sensor assembly having a base and an upper slide member moveable toward and away from said base, said upper slide member including at least one interference member that generates an interference fit between said emitter and said interference member thereby securely mounting said emitter to said upper slide member.

2. A vehicle occupant sensing system as set forth claim 1, wherein said upper slide member includes a retainer which supports said emitter, and said interference member is an arm extending into said retainer over an upper surface of said emitter.

3. A vehicle occupant sensing system as set forth in claim 1, wherein said upper slide member includes a retainer defining an inner surface, and said interference member is an arm extending into said retainer, said emitter disposed between said inner surface of said retainer and said arm.

4. A vehicle occupant sensing system as set forth in claim 1, wherein said interference member is a continuous ridge extending over an upper surface of said emitter.

5. A vehicle occupant sensing system as set forth in claim 1, wherein said upper slide member includes a retainer defining an inner surface, and said interference member is a continuous ridge extending into said retainer, said emitter disposed between said inner surface of said retainer and said continuous ridge.

6. A vehicle occupant sensing system as set forth in claim 1, wherein said interference member is integrally attached to said upper slide member.

7. A vehicle seat assembly comprising:

a seat cushion; and

a vehicle occupant sensing system disposed spaced relative to said seat cushion, said vehicle occupant sensing system comprising;

at least one emitter;

at least one sensor disposed relative to said emitter and operable to detect relative distance between said emitter and said sensor to thereby detect a condition of said seat cushion; and

at least one sensor assembly having a base and an upper slide member moveable toward and away from said base, said upper slide member including at least one interference member that generates an interference fit between said emitter and said interference member to thereby securely mount said emitter to said upper slide member.

8. A vehicle seat assembly as set forth in claim 7, wherein said upper slide member includes a retainer which supports said emitter and said interference member is an arm extending into said retainer over an upper surface of said emitter.

9. A vehicle seat assembly as set forth in claim 7, wherein said upper slide member includes a retainer defining an inner surface, and said interference member is an arm extending into said retainer, said emitter disposed between said inner surface of said retainer and said arm.

10. A vehicle seat assembly as set forth in claim 7, wherein said interference member is a continuous ridge extending over an upper surface of said emitter.

11. A vehicle seat assembly as set forth in claim 7, wherein said upper slide member includes a retainer defining an inner surface, and said interference member is a continuous ridge extending into said retainer, said emitter disposed between said inner surface of said retainer and said continuous ridge.

12. A vehicle seat assembly as set forth in claim 7, wherein said interference member is integrally attached to said upper slide member.
