Abstract

A seatbelt buckle includes a frame operable to receive a seatbelt latch plate therein. A retainer is carried by the frame and movable between a latched position and an unlatched position. A resilient member is positioned between the frame and the retainer to urge the retainer toward the unlatched position. An actuator is positioned to lock the retainer in the latched position when activated.

First claim

What is claimed is:

1 . A seatbelt buckle, comprising:
a frame operable to receive a seatbelt latch plate; a retainer carried by the frame and movable between a latched position and an unlatched position; a resilient member positioned between the frame and the retainer to urge the retainer toward the unlatched position; an actuator positioned to lock the retainer in the latched position when activated, the actuator being an electronic solenoid including a pin, the pin being retracted when the actuator is deactivated and the pin being extended when the actuator is activated; an over-ride button positioned to retract the pin when the over-ride button is manually depressed; and a release button positioned to unlatch the retainer when the release button is manually depressed and the pin is retracted.

2 . The seatbelt buckle of claim 1 , wherein the over-ride button extends laterally with respect to a longitudinal axis of the frame.

3 . The seatbelt buckle of claim 1 , wherein the release button is coupled to the retainer.

4 . The seatbelt buckle of claim 1 , further comprising an arm moveable between an enable position and a disable position, the arm in the disabled position preventing the pin from extending.

5 . The seatbelt buckle of claim 4 , wherein the arm is coupled to a rack and pinion mechanism operative to move the arm between the enable position and the disable position.

6 . The seatbelt buckle of claim 5 , wherein the pinion is coupled to a cylinder operative to receive a vehicle key.

7 . The seatbelt buckle of claim 1 , wherein the retainer is slidably movable along a longitudinal axis of the frame.

8 . The seatbelt buckle of claim 7 , wherein at least a portion of the retainer extends laterally from the frame.

9 . The seatbelt buckle of claim 8 , wherein the actuator is positioned to block movement of the retainer along the longitudinal axis when activated.

10 . The seatbelt buckle of claim 1 , further comprising a housing surrounding the frame.

11 . The seatbelt buckle of claim 10 , wherein the release button is slidable along a longitudinal axis of the frame.

12 . The seatbelt buckle of claim 11 , wherein the actuator is positioned to block movement of the retainer along the longitudinal axis when activated.

13 . The seatbelt buckle of claim 1 , wherein the resilient member is a compression spring.

14 . The seatbelt buckle of claim 13 , wherein the resilient member extends along a longitudinal axis of the frame.

15 . A seatbelt buckle, comprising:
a frame operable to receive a seatbelt latch plate; a retainer carried by the frame and movable by the latch plate between a latched position and an unlatched position; a latching push-button mechanism positioned to selectively lock the retainer in the latched position; and a release button operable to release the latch plate from the latched position to the unlatched position when the release button is manually depressed and the latching push-button mechanism is unlocked from the retainer.

16 . The seatbelt buckle as set forth in claim 15 , further comprising a resilient member positioned between the frame and the retainer to urge the retainer toward the unlatched position.

17 . The seatbelt buckle as set forth in claim 15 , wherein the latching push-button mechanism includes a plunger extendable into a path of the retainer from the latched position to the unlatched position when the retainer is in the latched position.

18 . The seatbelt buckle as set forth in claim 17 , further comprising a resilient member positioned between the frame and the retainer to urge the retainer toward the unlatched position.

19 . The seatbelt buckle of claim 15 , further comprising an arm moveable between an enable position and a disable position, the arm in the disabled position preventing the latching push-button mechanism from locking the retainer in the latched position.

20 . The seatbelt buckle of claim 19 , wherein the arm is coupled to a rack and pinion mechanism operative to move the arm between the enable position and the disable position.
