Vehicle occupant restraint belt buckle including illumination
First Claim
1. For use in a vehicle occupant restraint belt system including at least one belt portion for restraining a vehicle occupant, a buckle for detachably securing a keeper of the belt system to secure the belt portion across the occupant, said buckle comprising:
- a hollow housing including a translucent portion that defines an exterior surface portion of the housing;
a latch member mounted within the housing for movement between latched and unlatched positions to detachably secure the keeper;
an electrically energized light source that is mounted within the housing and that, when energized, continuously provides illumination outwardly from the buckle housing through the translucent portion; and
electrical connectors within the housing for connecting the light source to a power supply so as to thereby energize the light source and provide illumination through the translucent portion.

Abstract
A vehicle occupant restraint belt buckle (24) for detachably securing a keeper (26) to secure a belt portion (22) is disclosed as including a hollow housing (32) including a translucent portion (38) and receiving a latch member (40) that is moved between latched and unlatched positions to detachably secure the keeper. An electrically energized light source (52) is mounted within the housing (32) to provide illumination through the translucent portion (38). Electrical connectors (64,65) within the housing (32) connect the light source (52) to a power supply so as to thereby energize the light source and provide illumination through the translucent portion (38). In one construction, the translucent portion (38) comprises a plastic button (68) that operates the latch member and, in another construction, the translucent portion (38) is spaced from the button that controls the latch member and is embodied either by an extremity of the light source or a separate component. A switch (74) is also preferably incorporated into the buckle and controls light source energization in response to the secured or detached condition of the keeper (26) by the latch member (40). Different embodiments of the restraint belt buckle include a single light source (52) and a pair of light sources (52,54) which may be embodied by electrical bulbs, light emitting diodes that each emit light of a single color, or a bipolar light emitting diode that selectively and alternately emits light of two different colors.

12. For use in a vehicle occupant restraint belt system including at least one belt portion for restraining a vehicle occupant, a buckle for detachably securing a keeper of the belt system to secure the belt portion across the occupant, said buckle comprising:
-
a hollow housing including a translucent portion that functions as a manually operable latch member operator; a latch member mounted within the housing for movement between latched and unlatched positions to detachably secure the keeper under the control of the translucent latch member operator; an electrically energized light source that is mounted within the housing and that, when energized, continuously provides illumination outwardly from the buckle housing through the translucent latch member operator; electrical connectors within the housing for connecting the light source to a power supply so as to thereby energize the light source and provide illumination through the translucent portion; and a switch that controls energization of the light source in response to the secured or detached condition of the keeper by the latch member.

13. For use in a vehicle occupant restraint belt system including at least one belt portion for restraining a vehicle occupant, a buckle for detachably securing a keeper of the belt system to secure the belt portion across the occupant, said buckle comprising:
-
a hollow housing including a translucent portion that functions as a manually operable latch member operator; a latch member mounted within the housing for movement between latched and unlatched positions to detachably secure the keep under the control of the translucent latch member operator; an electrically energized light source that is mounted within the housing and that, when energized, continuously provides illumination outwardly from the buckle housing through the translucent latch member operator, and said light source being selected from the group consisting of a bulb and a light emitting diode; electrical connectors within the housing for connecting the light source to a power supply so as to thereby energize the light source and provide illumination through the translucent portion; and a switch that controls energization of the light source in response to the secured or detached condition of the keeper by the latch member.
