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.

Slide rail device for vehicle seat

A slide rail device for a vehicle seat including a lower rail member fixed on a floor of the vehicle and an upper rail member slidably fitted in the lower rail member. Basically, a stopper and a notch are provided respectively at the forward and rearward ends of the upper rail member, while a striker is provided at the floor of the vehicle, erecting therefrom. When the upper rail member is located at a home position upon the lower rail member, the stopper is abutted against the forward end of the upper rail member and side of the floor, with the notch being engaged over the striker, whereby the upper rail member is prevented against separation from the lower rail member. Another striker and hook-like lock member may be provided in the case where the vehicle seat is of a jump-seat type having a seat belt anchor, so that not only the seat is locked to the upper rail member against forward jumping, but also an upwardly slant pulling force applied through the seat belt anchor is dispersed and escaped to the floor through the stopper, two strikers, the lock member and the notch. Further, a guide roller arrangement is provided at the upper rail member for supportive sliding in the lower member, which includes a guide piece at one of the guide rollers that will be exposed from the lower rail member when the upper rail member is slid away from the lower rail member, such that the exposed portion of the upper rail member can be withdrawn into the lower rail member, with guiding aid of the guide piece.

Safety apparatus for arresting the fall of a worker

A safety apparatus for use by a worker on an elevated structure is disclosed. The purpose of the apparatus is to arrest the fall of the worker should they fall. Broadly the apparatus comprises at least two support posts having an upper end and a lower end supported on the structure and spaced apart from each other on the structure. Each support post has an I-shaped cross sectional configuration. The apparatus also includes a clamp on the lower end of each support post for clamping the post to the structure. The clamp itself comprises a base plate fast with the support post, a secondary plate or clamping plate spaced beneath the base plate, and fastening elements for drawing the two plates, towards each other with a member of the structure firmly clamped there between. The base plate projects laterally outwardly from the post on two opposed sides of the post, and defines at least one slot aperture on each said opposed side of the post through which the fastening elements are passed. Each post also has connecting formations towards the upper end thereof and an overhead safety line extending between said posts at a height of 1.7 to 2.0 metres above the member on which the posts are mounted. Each worker who works on the structure is fitted with a harness and a safety lead that can be releasably clipped to the safety line. This arrests the workers should they fall.
