Description
Technical Field of the Invention
The present invention relates to a restraining harness for securing a passenger to a vehicle seat.
Background of the Invention
Seat belts are commonly used in passenger vehicles to secure a passenger to a seat, the seat belt typically fastens around the waist of the passenger. In the event of an accident, the seat belt restrains the passenger to the seat instead of the passenger experiencing free flight in the cab of the vehicle. Seat belts in modern vehicles include a shoulder strap and a waist strap to better restrain the passenger's torso to the seat and the seat back in the event of an accident.
Restraint harnesses have been commonly used in vehicles to secure children passengers to bench seats. For example, U.S. Pat. No. 4,226,474 issued to Rupert et al. discloses a restraint vest that utilizes a pair of straps that laterally encircle the torso of the wearer with a pair of straps that extend from the anterior side of the torso over the shoulders to the posterior side of the torso. Anchoring straps are secured to the seat back or to the floor and fasten to the posterior side of the vest.
Nevertheless, the restraint harnesses of the past do not have the capability to accept passengers of varying torso sizes, such as torso width and torso length.
