Seatbelts - are usually "lap-sash" (or three-point) restraints which run diagonally from the shoulder to the hip as well as across the lap.

Lap-only belts are today regarded as inadequate, though are commonly found in the centre-rear position of many budget cars, as well as some luxury European cars.

Pretensioners tighten during an accident to give added protection.

Adjustable anchors alter the height of the shoulder strap to improve belt fit, and are especially helpful for smaller people.
