an electrical connector for providing electrical connection between the sensor and the electronic control unit, the electrical connector comprising;

a first contact member secured to either the base portion or the carrier portion, the first contact member having a plurality of contact surfaces; and

a second contact member secured to either the base portion or the carrier portion, the second contact member having a plurality of spring biased contacts movably secured to the second contact member, wherein the plurality of contact surfaces of the first contact member are configured to make contact with the plurality of spring biased contacts when the carrier portion is secured to the base portion.

2. The child seat as in claim 1, wherein the plurality of spring biased contacts each comprise an elongated portion for slidably passing through an opening in a housing of the second contact member.

3. The child seat as in claim 2, wherein the plurality of spring biased contacts each comprise a head portion configured to prevent the elongated portion from completely passing through the opening in the housing.

4. The child seat as in claim 3, wherein the second contact member further comprises a plurality of springs disposed in the housing, wherein each of the plurality of springs are configured to make electrical contact with a respective one of the plurality of contacts while also providing a termination end that depends away from an exterior surface the housing, wherein each of the plurality of springs also provides a biasing forced to a respective one of the plurality contacts.

5. The child seat as in claim 4, wherein the plurality of springs are configured to have a portion received within a slotted opening of the housing.

6. The child seat as in claim 5, wherein the plurality of springs are configured to provide a cantilever spring for providing a biasing forced to the plurality of spring biased contacts.

7. The child seat as in claim 6, wherein the plurality of springs are arranged in an alternating fashion within a receiving area of the housing.

8. The child seat as in claim 5, wherein the plurality of springs are each configured to have a U shaped portion positioned on a distal end, wherein the U-shaped portion is position to make contact with the head portion of the plurality of contacts.

9. The child seat as in claim 8, wherein the plurality of springs are each configured to have a taper from a point of securement to the housing towards the distal end, wherein the taper provides the biasing force to the plurality of contacts.

10. The child seat as in claim 4, wherein the plurality of springs are each configured to have a U shaped portion positioned on a distal end, wherein the U-shaped portion is position to make contact with the head portion of the plurality of contacts.

11. The child seat as in claim 4, wherein the plurality of contact surfaces of the first contact member are configured to provide a substantially larger contact surface area than a respective one of the plurality of spring biased contacts of the second contact member.

12. The child seat as in claim 3, wherein the second contact member further comprises a plurality of springs disposed within the housing, wherein each of the plurality of springs are configured to make electrical contact with a respective one of the plurality of spring biased contacts while also providing a termination end that provides electrical contact with a termination pad of the housing.

13. The child seat as in claim 1, wherein the second contact member further comprises a housing having a shoulder portion configured to engage an angular surface of the first contact member when the carrier portion is being secured to the base portion.

14. The child seat as in claim 1, wherein the electrical connector is configured to provide tolerances in three separate directions.

15. The child seat as in claim 14, wherein one of the three separate directions is substantially the same direction as that of the plurality of spring biased contacts movably secured to the second contact member.
