Abstract
Abstract A magnet-inclusive component is furnished for use in an occupant protecting system, such as a seat belt system, for a motor vehicle. The component includes a magnet and at least one member located adjacent the magnet. The magnet is molded or cast in situ in the adjcent member, preferably by integrally incorporating a magnetizable member in the adjacent member upon formation of the latter by molding or casting and then subjecting the magnetizable member to magnetization.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
57 words
In a magnet-inclusive component suitable for use in an occupant protecting means for a motor vehicle, said component having a magnet and at least one member located adjacent the magnet, the improvement wherein the adjacent member has a melting point lower than the magnet and the magnet is molded or cast in situ in the adjacent member.
Claim 2
Dependent Claim
57 words
In a magnet-inclusive component suitable for use in an occupant protecting means for a motor vehicle, said component having a magnet and at least one member located adjacent the magnet, the improvement wherein the adjacent member has a melting point lower than the magnet and the magnet is molded or cast in situ in the adjacent member.
Claim 3
Dependent Claim
25 words
The component of claim 1, further comprising an anti-separation means for the magnet, said anti-separation means being provided between the magnet and the adjacent member.
Claim 4
Dependent Claim
41 words
The component of claim 2, wherein the anti-separation means comprises at least one bore formed in the magnet and a matching projection formed of the same material as the adjacent member and extending as an integral part from the adjacent member.
Claim 5
Dependent Claim
41 words
The component of claim 2, wherein the anti-separation means comprises at least one groove formed in the magnet and a matching ridge formed of the same material as the adjacent member and extending as an integral part from the adjacent member.
Claim 6
Dependent Claim
27 words
The component of claim 2, wherein the anti-separation means comprises at least one projection formed on the magnet and a matching recess formed in the adjacent member.
Claim 7
Dependent Claim
26 words
The component of claim 1, wherein a surface of the magnet is exposed to the outside, flush relative to a surrounding surface of the adjacent member.
Claim 8
Dependent Claim
27 words
The component of claim 1, wherein a surface of the magnet is exposed to the outside and is raised from a surrounding surface of the adjacent member.
Claim 9
Dependent Claim
141 words
In a magnet-inclusive component suitable for use in a passive seat belt assembly, said assembly having a guide rail, a slider operatively movable along the guide rail, an emergency release buckle secured on the slider, a tongue releasably latched in the buckle, a magnet holder movably provided in the buckle, a magnet provided integrally with the magnet holder and movable between a first position which the magnet assumes while the tongue is not inserted in the buckle and a second position which the magnet takes while the tongue is inserted in the buckle, and a magnetic sensor for generating a different output signal depending whether the magnet is at the first position or the second position, the improvement wherein the holder has a melting point lower than the magnet and the magnet is molded or cast in situ in the holder.
