Vehicle transmission shift safety system
First Claim
1. A method of controlling the use of an automotive vehicle having a brake pedal (22), an engine, a transmission with a plurality of shift positions and an occupant restraint (12) for an operator movable between an unfastened position and a fastened position, said method comprising the steps of:
- initiating operation of the vehicle, blocking the shifting of the transmission between shift positions in response to the occupant restraint being in the unfastened position, monitoring a fastening frequency of fastening the occupant restraint after initiating operation of the vehicle, and removing the blocking of the shifting in response to the fastening frequency of the occupant restraint (12) being above a predetermined value.

Abstract
The invention discloses an assembly and method of controlling the use of an automobile while encouraging the use of occupant restraints (12). The assembly consists of an actuator (16) that blocks the movement of the shift mechanism (10) until occupant restraint sensors (14) detect the occupant restraints (12) in the fastened positions or the expiration of the predetermined time. The length of the predetermined time must be long enough to frustrate the operator to fasten the occupant restraint (12). The predetermined time of blocking may be zero after the a pattern of consistent fastening of the restraint is established, with the blocking being reinstated if the pattern is broken by an unfastened restraint.
