Load limiters are designed to minimise seat belt inflicted injury in violent collisions. The simplest type of load limiter is a fold sewn into the belt webbing, which pulls apart when a high amount of force is applied to the belt. In response to the Congressional action, NHTSA once again amended FMVSS 208, requiring vehicles to come with a seat belt reminder system that gives an audible signal for 4 to 8 seconds and a warning light for at least 60 seconds after the ignition is turned on if the driver's seat belt is not fastened. [95] This is called a seat belt reminder (SBR) system. In the mid-1990s, the Swedish insurance company Folksam worked with Saab and Ford to determine the requirements for the most efficient seat belt reminder. One characteristic of the optimal SBR, according to the research, is that the audible warning becomes increasingly penetrating the longer the seat belt remains unfastened. [99] Efficacy [ edit ]

child seats and restraints that are securely attached to the vehicle using Isofix, carabiners, ratchet straps, nuts and bolts etc In the European Union, all new long-distance buses and coaches must be fitted with seat belts. [125] Our first explanation uses a pendulum with a bottom weight. The pendulum is positioned directly below the retractor or spool. Remember, we said the retractor imitates the spool with a tooth-like edge.a) A seat belt load limiter fitted as original equipment obviously missing or a folded webbing type load limiter deployed It’s a small, light, inexpensive piece of metal that keeps the seatbelt from sliding freely by holding the lap and shoulder sides together very tightly.

The sensor activates the airbag light while the retractor grips the belt in place. It’s important to note that once the safety harness retractor is initiated during collision, it won’t work afterward. When driver side airbags became mandatory on all passenger vehicles in model year 1995 [ citation needed], most manufacturers stopped equipping cars with automatic seat belts. Exceptions include the 1995–96 Ford Escort/ Mercury Tracer and the Eagle Summit Wagon, which had automatic safety belts along with dual airbags.

Vattenfall, the Swedish national electric utility, did a study of all fatal, on-the-job accidents among their employees. The study revealed that the majority of fatalities occurred while the employees were on the road on company business. In response, two Vattenfall safety engineers, Bengt Odelgard and Per-Olof Weman, started to develop a seat belt. Their work was presented to Swedish manufacturer Volvo in the late 1950s, and set the standard for seat belts in Swedish cars. [15] The three-point seatbelt was developed to its modern form by Swedish inventor Nils Bohlin for Volvo—who introduced it in 1959 as standard equipment. [16] In addition to designing an effective three-point belt, Bohlin demonstrated its effectiveness in a study of 28,000 accidents in Sweden. Unbelted occupants sustained fatal injuries throughout the whole speed scale, whereas none of the belted occupants were fatally injured at accident speeds below 60mph. No belted occupant was fatally injured if the passenger compartment remained intact. [17] Bohlin was granted U.S. Patent 3,043,625 for the device. [13]

Generally, passengers who choose not to wear restraints in a vehicle modified to accept 3-point restraints receive marginally more severe injuries." [128] Airplanes [ edit ] An airplane lap seatbelt
