Energy converter for a safety belt
First Claim
1. An energy converter for a safety belt, the energy converter comprising a sleeve having an interior defined by an interior surface, a belt band of the safety belt being attached to the sleeve, a bolt having a bolt shank extending into the interior of the sleeve, the bolt having an end mounted so as to be non-rotatable in a stationarily attached belt fitting, at least one deformation member comprising a wire section having a sleeve leg and an arresting leg, the sleeve leg and the arresting leg extending at angle relative to each other, the sleeve having an end face, the arresting leg being fixedly attached to the bolt shank at the end face of the sleeve, the bolt shank having an axis, the interior surface of the sleeve defining a groove extending in an axial direction, the sleeve leg extending in the axial direction and being slidably supported in the groove of the sleeve, wherein the groove has a cross-section which coincides with the cross-section of the sleeve leg, and wherein the arresting leg contacts the bolt shank.

Abstract
An energy converter comprises a sleeve with a sleeve channel. A longitudinal groove is configured in the wall of the sleeve channel. A shank of a bolt is introduced into the sleeve channel. An L-shaped deformation member having an arresting leg is introduced into a lateral bore of the bolt shank, wherein then the sleeve leg comes to rest in the longitudinal groove of the sleeve and at the outer surface of the bolt shank. The sleeve and the bolt are thus secured against rotation. The bolt has a hexagonal bolt head, which can be positionally fixed in a matchingly configured aperture in the cheek of the belt fitting. If a predetermined force F acts upon the belt band, the sleeve and the bolt turn relative to one another and the deformation member pulls out of the longitudinal groove while rolling around the bolt shank.
