Abstract: An illuminated safety restraint system including a buckle assembly adapted to selectively releasably engage a corresponding clip. The buckle assembly includes a housing having an inner chamber defined therein, an outer surface, and at least one aperture extending between the outer surface and the inner chamber. A receiver is disposed in the inner chamber for releasably engaging the clip. A button is attached to the housing in the inner chamber, and is in communication with the receiver for selectively releasing the clip from the receiver. A cover is attached to the outer surface of the housing and has a lower surface spaced from the outer surface of the housing to define a cover chamber adjacent the aperture of the housing. A light module is disposed in the cover chamber adjacent the aperture for selectively emitting light so as to illuminate at least a portion of the button.

Abstract: In a crimped hose, a length of rubber tubing is crimped into a blind-ended ferrule. To determine whether the tubing has been fully inserted, a dimple is pressed into the ferrule. The force needed to produce the dimple is small or large, depending whether the rubber is inserted properly, and the difference is large enough to serve as a detector. Measuring the dimple-force provides a commercially-useful test for proper insertion.

Abstract: The headrest support tubes are secured to the seat frame member not by the usual welding, but by gripping the web of the member between two rings or lock-beads swaged into the metal of the tube. The first ring is swaged-out by compressing the tube. The tube, with the one ring, is then assembled into a through-hole in the web of the frame member. Then, the second ring is swaged into the metal of the tube, on the other side of the web, and the web lies gripped between the rings. The seat frame member may be an I-section extrusion, or a round tube with localised squeezed-flat areas, flanked by flanges.

Abstract: Headrest-mounting-tubes are attached into the seatframe of an automotive seat. Headrest-posts engage the mounting-tubes, and support the headrest. The headrest-posts need to be orientated correctly, and so have a key that engages a keyway in the mounting-tube. The keyway is formed as a keyway-pocket, being punched from the open end of the tube. Preferably, the keyway-pocket is punched after the mounting-tube has been attached into the seatframe.

Abstract: A fluid flow regulator for a turbocharged internal combustion engine includes a body and a valve. The body defines a chamber and includes first, second and third ports. The chamber is in fluid communication with the first, second and third ports. A first fluid flow path passes through the first port, through the chamber and through the second port.

The valve is movable between first and second configurations with respect to the body. The first configuration substantially occludes the second fluid flow path, the second configuration substantially occludes the first fluid flow path, and the plurality of intermediate configurations permit restricted fluid flow along the first and second fluid flow paths.

Abstract: A method of managing fuel vapor pressure in a fuel system. The method includes locating between first and second ports a poppet and a seal cooperating with the poppet, positioning the seal in a substantially symmetrically deformed configuration so as to sense a negative pressure at a first pressure level, positioning the seal in a generally asymmetrically deformed configuration so as to vent negative pressure below the first pressure level, and positioning the seal in an undeformed configuration so as to vent positive pressure above a second pressure level. The poppet is movable along an axis. And the seal is flexible between the undeformed configuration when disengaged from the poppet, the substantially symmetrically deformed configuration when engaged with the poppet, and the generally asymmetrically deformed configuration when engaged with the poppet.

The coupling member conveys motive force of the device to rotation of the closure member. And the sensor detects the angular position of the rotor with respect to the stator.

The system includes a valve having first and second ports in communication with a first chamber and a third port in communication with a second chamber, the first and second chambers being defined by a metering member that divides an internal volume of a housing.

The diagnostic member provides the ability to reliably measure flow through the valve. The system can use two (2) hoses including three (3) connections from a vapor supply port connected with the first port to the third port operatively connected with a manifold.
