Problems solved by technology

Many newer cars also have rear seat designs that are movable to provide fore and aft sliding adjustment and storage positions such as by flipping and folding, thus having the same harness design and manufacturing issues as the front seats
Additionally, the rear seats in minivans, sport utility vehicles, and off-road vehicles are removable, creating the advantage of easily disconnecting the harness when the rear seat is removed from the vehicle and reliably reconnecting the harness when the rear seat is reinstalled.

Embodiment Construction

[0016] Seat belt reminder systems may include a power source, such as a battery, that may be isolated from the vehicle's electrical system. The seat belt reminder system can also be configured to provide wireless communication between the occupant sensor assembly and the buckle sensor, both located within the seat assembly, and a vehicle controller, such as an air bag system located within the vehicle. Therefore, there is no need to provide a wiring harness for transmitting signals between the occupant sensor assembly and the buckle sensor in the seat assembly and the vehicle controller, or to provide power to the occupant sensor assembly and the buckle sensor.

Abstract

A seat belt reminder system (10) includes an occupant sensor (12) to detect an occupant (14) in a seat (18) of a vehicle (20) and a buckle sensor (22) to detect when a seat belt (28) is latched to a seat belt buckle (24). A controller (40) detects whether the seat belt buckle (24) is latched and a wireless transmitter (42) sends the buckle status to a remote receiver (30) in the vehicle (20). The controller (40) and transmitter (42) are powered by a battery (44) that is separate from the vehicle electrical system (32). The controller (40), transmitter (42), and battery (44) may be incorporated into the occupant sensor (12). A separate power supply for the controller (40) and transmitter (42) and a wireless connection to the receiver (30) in the vehicle (20) eliminates the need for a wiring harness from the seat (18) to the vehicle (20). The seat belt reminder system (10) may provide long battery life by connecting the controller (40) and transmitter (42) to the battery (44) only when the seat is occupied.

Description

technical field [0001] The present invention relates generally to seat belt systems for vehicles, and more particularly to systems for determining whether an occupant of a vehicle seat is properly buckled up. Background technique [0002] The seat belt reminder system is configured to determine whether an occupant of a seat in a vehicle has properly buckled a seat belt tongue into a seat belt buckle. If the passenger is not properly fastening the seat belt into the seat belt buckle, the passenger may be reminded to check and properly fasten the seat belt tongue into the seat belt buckle. As described herein, a tongue refers to any structure used to fasten a seat belt into a seat belt buckle. [0003] The current state of the art on seat belt reminder systems uses occupant sensors to monitor whether a passenger is seated in a seat combined with a buckle sensor to monitor whether the occupant's seat belt is properly fastened. The occupant and buckle sensors are typically con...
