  • Safety belt retractors
    Patent number: 4256273
    Abstract: A safety belt retractor has a spindle 11 provided with an outer layer 14 formed of a material which is capable of absorbing energy by substantially inelastic deformation. When the safety belt 10 is subject to shock-loading exceeding a predetermined level, this outer layer 14 is crushed, leading to a reduction in the effective diameter of the spindle 11 and thereby allowing an additional length of the belt 10 to be paid out after the spindle 11 has been loaded.
