No one gets the cold shoulder with Autoliv's two-point seatbelt

Autoliv's two-point belt debuts in the tiny Renault Twizy, which has only one front seat.

A seatbelt innovation from Autoliv covers the shoulder that is unprotected in the conventional three-point belt. The company's vertically oriented two-point belt supplements the three-point, the latter of which is very effective in frontal crashes but less so in other types such as side-impact, rollover, and crashes in which the vehicle rotates. The two-point is helpful in those types of crashes but has value in frontal ones as well, Autoliv says, by helping better distribute chest impact forces. The company claims that tests show the two-point reduces the risk of severe injuries and fatalities by approximately 30%. Autoliv further claims that the benefits of the alternative system providing protection to both shoulders—the four-point belt—are lost because some drivers find the inconvenience of using two hands to buckle reason for not using it at all. There is no buckling with the two-point, which is fixed at both ends and requires the seat occupant to merely slide a shoulder under it.
