Force limiter for belt retractor, has torsion bar, which is twisted for limiting force and torsion bar has austenitic steel or dual phase steel and torsion bar consists of cold transformable steel or twinning induced plasticity steel
摘要
<p>The force limiter (18) has a torsion bar (19), which is twisted for limiting the force. The torsion bar has austenitic steel or a dual phase steel. The torsion bar consists of cold transformable steel or twinning induced plasticity (TWIP) steel or duplex steel or transformation induced plasticity (TRIP) steel or stainless steel.</p>
