Abstract

A seatbelt buckling device and system includes a buckle and a latch plate. The latch plate includes a pair of fingers that extend from a base portion. The buckle includes buckle housing that defines a slot that is configured to receive the fingers of the latch plate. The buckle also includes a blocking member disposed in the slot that splits the slot into first and second slot portions. The first and second slot portions are sized to receive the fingers. The blocking member restricts debris from entering a cavity of the buckle housing. The buckle further includes a depressible button for releasing the latch plate. The blocking member is arranged as a blockout portion integrated into the button or an ejector protrusion extending from an ejector disposed within the buckle.

First claim

The invention claimed is:

1. A buckling device for retaining a seatbelt for use in a passenger vehicle, the device comprising:
a seatbelt buckle configured to receive and retain a latch plate having two latchable finger portions, the seatbelt buckle including a housing adapted for mounting to a vehicle structure, the housing defining an internal cavity, the housing defining a first direction of insertion for the latch plate;
a button disposed within the housing and reciprocally moveable in the first direction relative to the housing;
an insertion slot having an overall width defined at least in part by the buckle housing and the button, the insertion slot defining an opening; and
a blockout portion being moveable in the first direction relative to the housing and disposed in the insertion slot, the blockout portion blocking a portion of the opening and defining first and second slot portions, wherein the widths of the first and second slot portions are smaller than the overall width of the insertion slot;
wherein the first and second slot portions are configured to receive first and second finger portions of the latch plate.

2. A buckling device for retaining a seatbelt for use in a passenger vehicle, the device comprising:
a seatbelt buckle configured to receive and retain a latch plate having two latchable finger portions, the seatbelt buckle including a housing adapted for mounting to a vehicle structure, the housing defining an internal cavity;
a button disposed within the housing and reciprocally moveable relative to the housing
an insertion slot having an overall width defined at least in part by the buckle housing and the button, the insertion slot defining an opening; and
a blockout portion being moveable relative to the housing and disposed in the insertion slot, the blockout portion blocking a portion of the opening and defining first and second slot portions, wherein the widths of the first and second slot portions are smaller than the overall width of the insertion slot;
wherein the first and second slot portions are configured to receive first and second finger portions of the latch plate;
wherein the buckle includes a reciprocating latch member disposed within the housing, the latch member configured to retain the latch plate inserted through the first and second slot portions.

3. The device of claim 2 , wherein the latch member includes a pair of posts configured to retain the latch plate finger portions.

4. A buckling device for retaining a seatbelt for use in a passenger vehicle, the device comprising:
a seatbelt buckle configured to receive and retain a latch plate having two latchable finger portions, the seatbelt buckle including a housing adapted for mounting to a vehicle structure, the housing defining an internal cavity;
a button disposed within the housing and reciprocally moveable relative to the housing
an insertion slot having an overall width defined at least in part by the buckle housing and the button, the insertion slot defining an opening; and
a blockout portion being moveable relative to the housing and disposed in the insertion slot, the blockout portion blocking a portion of the opening and defining first and second slot portions, wherein the widths of the first and second slot portions are smaller than the overall width of the insertion slot;
wherein the first and second slot portions are configured to receive first and second finger portions of the latch plate;
wherein the blockout portion is integrally formed with the button and moves with the button.

5. The device of claim 1 , further comprising an ejector disposed within the housing, wherein the ejector is biased toward the opening and reciprocally moveable within the housing, wherein the ejector will translate away from the opening in response to insertion of the latch plate into the insertion slot.

6. A buckling device for retaining a seatbelt for use in a passenger vehicle, the device comprising:
a seatbelt buckle configured to receive and retain a latch plate having two latchable finger portions, the seatbelt buckle including a housing adapted for mounting to a vehicle structure, the housing defining an internal cavity;
a button disposed within the housing and reciprocally moveable relative to the housing
an insertion slot having an overall width defined at least in part by the buckle housing and the button, the insertion slot defining an opening; and
a blockout portion being moveable relative to the housing and disposed in the insertion slot, the blockout portion blocking a portion of the opening and defining first and second slot portions, wherein the widths of the first and second slot portions are smaller than the overall width of the insertion slot;
wherein the first and second slot portions are configured to receive first and second finger portions of the latch plate;
an ejector disposed within the housing, wherein the ejector is biased toward the opening and reciprocally moveable within the housing, wherein the ejector will translate away from the opening in response to insertion of the latch plate into the insertion slot;
wherein the ejector includes an ejector protrusion extending toward the opening, and the blockout portion comprises the ejector protrusion.

7. The device of claim 1 , wherein the first and second slot portions have the same width.

8. A buckling device for retaining a seatbelt for use in a passenger vehicle, the device comprising:
a seatbelt buckle configured to receive and retain a latch plate having two latchable finger portions, the seatbelt buckle including a housing adapted for mounting to a vehicle structure, the housing defining an internal cavity;
a button disposed within the housing and reciprocally moveable relative to the housing;
an insertion slot having an overall width defined at least in part by the buckle housing and the button, the insertion slot defining an opening; and
a blockout portion being moveable relative to the housing and disposed in the insertion slot, the blockout portion blocking a portion of the opening and defining first and second slot portions, wherein the widths of the first and second slot portions are smaller than the overall width of the insertion slot;
wherein the first and second slot portions are configured to receive first and second finger portions of the latch plate
wherein the first and second slot portions have the same width;
wherein the blockout portion is centered on a longitudinal axis of the buckle.

9. The device of claim 1 , wherein the first and second slot portions have different widths.

10. The device of claim 1 , wherein the blockout portion is offset from a longitudinal axis of the buckle.

11. The device of claim 3 , wherein the latch member pivots in response to actuation by the button, and the posts move in unison along with the latch member.

12. A buckling system for retaining a seatbelt for use in a passenger vehicle, the system comprising:
a latch plate having a base portion and first and second fingers extending from the base portion;
a seatbelt buckle configured to receive and retain the fingers of the latch plate, the seatbelt buckle including a housing adapted for mounting to a vehicle structure, the housing defining an internal cavity, the housing defining a first direction corresponding to a direction of insertion of the latch plate;
an insertion slot defined at least in part by the buckle housing, the insertion slot defining an opening; and
a blockout portion disposed in the insertion slot, the blockout portion blocking a portion of the opening and being moveable in the first direction;
the insertion slot having first and second slot portions defined by
