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 emittting diode that selectively and alternately emits light of two different colors.

    • A reversible ratchet wrench (10) includes a wrench body (11) having a unitary head (12) including an opening (20) with circular driver and pawl portions (22, 24) having cylindrical shapes which facilitate manufacturing and support of a driver (36) and a pawl (38) upon assembly. The driver (26) has a ratchet portion (28) received within the driver portion (22) of the opening and includes ratchet teeth (30) that extend between oppositely facing surfaces 16, 18) of the wrench head (12). The pawl (38) is received within the pawl portion (24) of the opening (20) and includes teeth (40a, 40b) that extend between the wrench head surfaces (16, 18) and provide continuous engagement therebetween for selective locking of the driver in one direction and ratcheting in the other direction. Such continuous engagement of the teeth for the full distance between the oppositely facing surfaces (16, 18) of the head permits the wrench to carry a large amount of torque with a relatively thin construction. A ball (34) of a releasable detent mechanism (35) is provided to secure a socket to a driving lug (32) of the driver (26). A tab (42) of pawl (38) is provided for changing the direction of locking, and a spring biaser (44) operates on the pawl for maintaining the pawl teeth (40a or 40b) in engagement with the ratchet teeth (30) on the driver in order to provide locking in one direction and ratcheting in the other direction.
