4908 results about "Belt safety" patented technology

A woman buckling a 3-point seat belt. A seat belt (also known as a seatbelt or safety belt) is a vehicle safety device designed to secure the occupant of a vehicle against harmful movement that may result during a collision or a sudden stop.

Sandal having active self-adjusting harness and method

A sandal having an active, self-adjusting harness and method therefore typically used in the out-of-doors for rigorous activities includes rubber and synthetic materials and exhibits a lightweight robust, high-strength, flexible construction including an elongated sole for supporting a foot where the sole has a toe end and a heel end. A center toe strap is anchored in the toe end and includes a distal end fixedly connected to a front buckle. A rear strap is anchored in the heel end and has a first end and a second end extending above the sole. The first end and the second end of the rear strap are respectively connected to an inside rear buckle and an outside rear buckle. A self-adjusting harness comprised of a single strap is anchored in the toe end. The single strap includes an inside end and an outside end each extending above the sole. The inside end of the single strap is circuited through the front buckle and the inside rear buckle while the outside end of the single strap is circuited through the front buckle and the outside rear buckle. The inside end and the outside end are engaged to form a closure over-the-instep of the foot. Finally, an independent adjustable heel strap is attached to the outside rear buckle and the inside rear buckle. Subsequent movements of the foot result in continuous adjustments in the tension of the single strap for regulating and equalizing the tension in the harness.

Smart seatbelt control system

InactiveUS20070096447A1Reducing potential of serious injury and deathReduce fatalityBelt retractorsElectric devicesOccupant safetyControl system
An apparatus for preventing occupant injury during accident has various features to ensure safety. A sensor 70, detecting seat belt engagement is provided. In addition, there is a means for varying the tension of a seatbelt 17, depending upon the weight of the occupant 110 and the speed of the vehicle carrying the occupant 110. When the occupant 110 seats on any of the seats 17, the load cell switch 18 will close, allowing the load cell output energy to energize the control module 25. The control module 25 will then enables the counter 50 to count the number of closed load cell switches 18. The control module 25 further enables an optoisolator switch configured with the sensor 70 to then energize a latching relay 80 operatively configured to check the seat belt latching of all occupied seats 10 with closed load cell switches 18, to assure occupants safety. The load cells are configured with strain gauges and temperature sensors to ensure human occupants. Such that, when the switch 18 for the occupied seat 10 is closed, the latching relay 80 circuit is energized so that the seat belt 17 for the occupied seat location is checked for buckling. The latching relay 80 circuit and the counter 50 circuit are operatively configured and closed only when an occupant 110 takes any of the seats 10. The latching relay switch 85 is only energized when the counter circuit 50 is closed.

RFID buckle closure and presence sensor system for safety childseat

In the preferred embodiment of the present invention a passive, wireless, RFID-based wireless buckle-closure sensor determines whether the buckle of a child safety seat is secured. Sensors also are provided to determine if the child is in the seat, the temperature and if the vehicle is in operation, and alarms are sounded if an unsafe condition is detected by the system. Child safety seats utilize a 3-point or 5-point locking-mechanism for seat belt and harness restraints. The locking-mechanism requires that metal belt / harness components latch together and are released by depression of a lock-mounted release button. In the preferred embodiment of the present invention a passive RF transponder is affixed to the buckle. Essentially the RF transponder comprises an RFID device without a data component. The RF transponder is interrogated by a frequency-scanning reader, which determines the resonant frequency of the transponder. The resonant frequency of the transponder is affected by the presence of the metal fittings local to the RF transponder. Thus, since the major components of the buckle and latch are metal, the detection of the change in the resonant frequency of the transponder, also referred to as “detuning,” permits the determination of the state of the belt / harness buckle—latched or unlatched. This sensing is wireless, unobtrusive, and requires only a passive component be attached to the buckle. Further disclosed is a method of determining the status of a child in a child safety seat, including: whether or not a child is in the seat, whether or not the belt / harness buckle is latched, whether the vehicle's engine is in operation, and whether or not the surrounding temperature exceeds the temperature range. If an unsafe condition is detected, an alarm is activated.
