Abstract

A seatbelt buckle that includes a housing, an attracting member, an attractable element, and a plate adapted to retain a seatbelt clip within the housing. The member, the element, and the plate may be carried by the housing. The buckle is adapted so that when the member is electronically actuated, the element causes the plate to move toward the member and thereby release the clip.

First claim

The invention claimed is:

1. A seatbelt buckle, comprising:
a housing;
an attracting member;
an actuator plate extending longitudinally along a first axis of the housing and carrying an attractable element; and
a base plate also extending along the first axis and adapted to retain a seatbelt clip within the housing, wherein the member, the actuator plate, and the base plate are carried by the housing;
wherein, when the member is electronically actuated, the element causes the actuator plate to drive the base plate along a second axis toward the member and release the clip, wherein the second axis is transverse to the first axis.

2. The seatbelt buckle of claim 1 , wherein the member is an electro-magnetic device.

3. The seatbelt buckle of claim 2 , wherein the member includes a magnetic core.

4. The seatbelt buckle of claim 1 , wherein the element is a magnetic core.

5. The seatbelt buckle of claim 1 , wherein a locking feature protrudes from one side of the actuator plate, wherein one end of the actuator plate is coupled to the housing, wherein, when the member is actuated, the element causes the actuator plate to resiliently flex and thereby release the clip.

6. The seatbelt buckle of claim 1 , wherein the actuator plate comprises a magnetic core responsive to the attracting member.

7. The seatbelt buckle of claim 1 , further comprising a sensor located at an opening of the housing.

8. The seatbelt buckle of claim 7 , wherein the sensor is a biometric sensor.

9. A seatbelt buckle, comprising:
a housing;
an attracting member;
an attractable element;
an actuator that comprises an actuator plate and a flange extending from the actuator plate, wherein the flange is coupled to and carries the element; and
a second plate adapted to retain a seatbelt clip within the housing, wherein the member, the element, the actuator, and the second plate are carried by the housing;
wherein, when the member is electronically actuated, the element causes the second plate to move toward the member and thereby release the clip.

10. The seatbelt buckle of claim 9 , wherein only one end of the actuator plate is coupled to the housing.

11. The seatbelt buckle of claim 9 , further comprising a sensor located at an opening of the housing.

12. The seatbelt buckle of claim 11 , wherein the sensor is a biometric sensor.

13. The seatbelt buckle of claim 9 , wherein the member or the element comprises a magnetic core.

14. A seatbelt buckle, comprising:
a housing;
a touch sensor;
an attracting member;
a lock; and
an actuator extending longitudinally along a first axis of the housing,
wherein the sensor, the member, the lock, and the actuator are carried by the housing, wherein, when the sensor is activated, the member generates a magnetic field causing the actuator to drive the lock toward the member along a second axis and thereby release a seatbelt clip, wherein the second axis is transverse to the first axis.

15. The seatbelt buckle of claim 14 , wherein the sensor is adapted to detect a fingerprint and provide an electronic output associated with the fingerprint.

16. The seatbelt buckle of claim 14 , wherein the member or the actuator includes an electromagnet.

17. The seatbelt buckle of claim 14 , wherein the member or the actuator includes an attractable element.

18. The seatbelt buckle of claim 17 , wherein the element is a magnetic core.

19. The seatbelt buckle of claim 14 , wherein the member, the lock, the actuator, or a combination thereof comprise a magnetic core.

20. The seatbelt buckle of claim 14 , wherein at least one of the lock or the actuator have a free end and an end coupled to the housing, wherein the free end moves in response to the member or the actuator being energized to generate the magnetic coupling.
