Impact absorption device, impact absorption device, impact absorption system and components containing the device

摘要

The invention relates to an impact absorption device including a guide profile (5A2).5B2；9A；Page: 11. Guide profile (6a);6B；10A；It can slide on the guide profile, which is characterized in that the guide profile is fixed on the guide profile by a fixing device (...),The guide profile absorbs the profile protrusion guided by the free end by impact, and the fixing device (14) is positioned on the guide profile and guides the profile with at least one tearing line according to the common longitudinal direction of the profile, so as to For each tear line, one of the guide profiles and one of the guide profiles has a low shear strength surface (19) extending in the longitudinal direction of the profile,A surface (19) with a lower shear strength has a shear strength less than that of other profile surfaces (14) which are not on the tear line and are configured to tear in the longitudinal direction of the profile under the action of the fastening device. The impact absorbing end of the guide profile is affected at a threshold.
