Filed:

Mar 16, 2008

Appl. No.:

12/049352

Inventors:

Anthony Lee - Davie FL, US

International Classification:

B60R 22/32

US Classification:

302984

Abstract:

The present invention provides an apparatus to facilitate the easy removal or release of a seatbelt or similar safety harness device during an emergency. The apparatus of the invention provides a practical and easy means of releasing a seatbelt or similar safety harness that is jammed or difficult to remove during an auto accident or other emergency. The apparatus is comprised of an Emergency Seatbelt Release (ESR) box which is attached to the seatbelt, preferably at or near the tongue connector of the seatbelt such that the seatbelt passes through the ESR box. The ESR box contains a sharp edged cutting instrument attached to a trigger handle contained in a compartment within the ESR box. The compartment containing the trigger handle has a protective quick access cover so that it will not be inadvertently pulled or snagged in non-emergency situations. When the protective cover is removed, the trigger handle becomes accessible with the aid of compression springs which extend and eject the trigger handle. In an emergency, the trigger handle is pulled and the sharp edge cutting instrument is drawn along the seatbelt, cutting it completely in one forward motion.

International Classification:

B23K 1124

US Classification:

219110

Abstract:

A method and apparatus are disclosed for analyzing the dynamic resistance of a resistance spot welding process to determine the time of an expulsion event and use that time as the weld completion time for controlling weld termination via a weld feedback signal, controlling automatic current stepping, and identifying maintenance needs. A preconditioning pulse is used to stabilize the weld process and aid in obtaining interpretable resistance information. After an initial blanking period the resistance curve is analyzed by calculating first and second derivative values and applying several algorithms that make possible the computer recognition of characteristic resistance curve shapes resulting from weld expulsion under good geometry, bad geometry and edge weld conditions.

Warren D. Hill - Lake Orion MI

Assignee:

General Motors Corporation - Detroit MI

International Classification:

B23K 1124

US Classification:

2191171

Abstract:

A method and apparatus are disclosed for resistance spot welding including applying a preconditioning pulse at the beginning of a welding process to stabilize the resistances at the interface of the sheets being welded and at the interface of the electrodes and the sheets. A current pulse is applied just after contact of electrodes and the workpiece when the electrode force is between about 10% and 75% of its final value to melt interface surfaces followed by a cooling time to permit dissipation of heat from the interfaces, and is finally followed by a conventional weld current schedule. The contact time is determined be electrically monitoring the conductivity between the electrodes as they are moved toward the workpiece. Alternatively, the applied electrode pressure is monitored to determine when sufficient electrode force is applied to the workpiece to achieve the proper resistance for the pulse application.
