Claim 11

A gear shifting lever assembly as set forth in claim 6, said radiant energy source means and said detector means being in said lever, said blocking portions comprising said arm on said knob.

Claim 12

A gear shifting lever assembly as set forth in claim 6 having first and second detent means for releasably coupling said arm to said lever adjacent to said front and rear stops respectively, each of said detent means being releasable upon application of a force to said knob which is less than the force required to move said lever in said to and fro directions.

Claim 13

A gear shifting lever assembly as set forth in claim 10, said arm having an end which is remote from said knob, said arm being pivotally connected to said lever adjacent to said end, said detent means being between said knob and said end of said arm.

Claim 14

A vehicle gear shifting lever assembly having signal generating means therein for generating a signal when said lever assembly is moved in to and fro directions during gear changing, said signal being usable to deenergize the ignition system of a vehicle during gear changing, said lever assembly comprising: a shift lever having a free end and having an opening extending into said lever from said free end, a shifting knob having an integral arm extending therefrom, said arm extending into said opening and having an end which is proximate to the inner end of said opening, said arm being pivotally connected to said lever at said end of said arm on a pivot axis which extends transversely of said to and fro directions whereby said knob and said arm can be moved in said to and fro directions relative to said lever, first and second detent means for releasably coupling said arm to said lever when said arm and knob are in front and rear positions relative to said lever respectively, said detent means being releasable upon application of a force to said knob which is less than the force required to move said lever in said to and fro directions, and signal generating means in said arm and lever, said signal generating means being effective to produce a signal when said knob and arm are moved relative to said lever in said to and fro directions whereby, said signal is usable to deenergize the ignition system of a vehicle during movement of said lever with accompanying gear changing.
