Apparatus with integral locking pin and cavity seal

An apparatus comprising:

• an integral locking pin having a head portion and a leg portion;
• and
• a mounting portion for mounting said apparatus to a mounting location with said integral locking pin, said mounting portion comprising a member having a first surface and a second surface orthogonal to said first surface, wherein said first surface and said second surface define a first portion of a cavity configured to accept said head portion of said integral locking pin when said integral locking pin is fully inserted into said cavity, and wherein said mounting portion further comprises a tapered surface defining a second portion of said cavity configured to accept said leg portion of said integral locking pin when said locking pin is fully inserted into said cavity.

A seat position sensor circuit comprising:

• a varistor coupled to a pair of terminals;
• and
• a forward biased diode having an input terminal and an output terminal, said input terminal coupled to said varistor and said output terminal coupled to a Hall switch, wherein a negative voltage may be applied at said pair of terminals to test said varistor and wherein said forward biased diode would isolate said Hall switch from said negative voltage.

A method of testing a varistor of a seat track position sensor circuit comprising the steps of:

• applying a negative voltage to test a break down voltage of said varistor;
• and
• blocking said negative voltage to effectively isolate other components of said circuit.

A method of securing a seat position sensor to a vehicle comprising the steps of:

• locating said sensor in proximity to a mounting portion of said vehicle, said mounting portion having an opening;
• and
• forcing an integral locking pin of said sensor into said opening of said mounting portion.
