Editing Seat belt (section)

====Belt-in-Seat====
The Belt-in-Seat (BIS) is a three-point harness with the shoulder belt attached to the seat itself, rather than to the vehicle structure. The first car using this system was the [[Range Rover Classic]], which offered BIS as standard on the front seats from 1970.<ref>{{cite web |last=Lankard |first=Tom |url= http://editorial.autos.msn.com/article.aspx?cp-documentid=434695 |title=The first seat offered in the US that incorporated a three-point belt—on the 1990 Mercedes-Benz SL |website=Editorial.autos.msn.com |access-date=2011-02-02 |archive-url= https://web.archive.org/web/20140727011325/http://editorial.autos.msn.com/article.aspx?cp-documentid=434695 |archive-date=2014-07-27 |url-status=dead }}</ref> Some cars, like the [[Renault Vel Satis]], use this system for the front seats.

Belt-in-Seat type belts have been used by automakers in convertibles and pillarless hardtops, where there is no "B" pillar to affix the upper mount of the belt. Chrysler and Cadillac are well known for using this design. Antique auto enthusiasts sometimes replace original seats in their cars with BIS-equipped front seats, providing a measure of safety not available when these cars were new. However, modern BIS systems typically use electronics that must be installed and connected with the seats and the vehicle's electrical system in order to function properly.{{citation needed |date=August 2013}}
