Abstract

An impact absorbing construction for a motor vehicle comprises an impact damping cylinder. One end of said impact damping cylinder is adapted for being fastened to a vehicle structure. The other end of the impact damping cylinder is connectable with a bumper. The bumper is adjustable with respect to the impact damping cylinder. In order to allow both a horizontal and a vertical adjustment, a sleeve is provided having a sleeve axis which is perpendicular to the cylinder axis. A core is received by the sleeve. The core is adjustable along the sleeve axis by screwing. The bumper is fixable to the core. A sleeve support is fastened to the sleeve. The sleeve support is connectable with the other end of the damping cylinder and is adjustable with respect to the damping cylinder along the cylinder axis.

Dependent claims

An impact absorbing construction for a vehicle comprising at least one impact damping cylinder unit (18) having a cylinder axis and two ends (18a, 18b), one (18a) of said two ends being adapted for being fastened to a vehicle structure (1) and the other (18b) of said two ends being connectable with a bumper element (2) by adjustable connection means (3),

said adjustable connection means (3) comprising a sleeve member (11) having a sleeve member axis substantially perpendicular to said cylinder axis, a core member (40) within said sleeve member (11), which core member (40) is adjustable along said sleeve member axis by thread engagement means, said bumper element (2) being fixable to said core member (40), a sleeve support member (12) being fastened to said sleeve member (11), an annular connecting member (14) being rotatably mounted within said sleeve support member (12) about a connecting member axis perpendicular to said sleeve member axis, said annular connecting member (14) being rotatable but axially and radially fixed with respect to said sleeve support member (12) along said connecting member axis, said annular connecting member (14) having internal thread means (15), said internal thread means (15) of said annular connecting member (14) being in engagement with external thread means (20) provided at said other end (18b) of said damping cylinder unit (18) thereby allowing said damper cylinder unit to be horizontally adjustable with respect to said sleeve support member and sleeve member.

said adjustable connection means (3) comprising a sleeve member (11) having a sleeve member axis substantially perpendicular to said cylinder axis, a core member (40) within said sleeve member (11), which core member (40) is adjustable along said sleeve member axis by thread engagement means, said bumper element (2) being fixable to said core member (40), a sleeve support member (12) being fastened to said sleeve member (11), said sleeve support member (12) being provided with a plurality of circularly arranged gripper elements (32) surrounding an external face provided at said damping cylinder unit (18) adjacent to said other end (18b) thereof, and a screw cap (34) being engageable in thread engagement with said sleeve support member (12), wherein said screw cap (34) acts onto said gripper elements (32) such as to radially engage said gripper elements (32) with said external face thereby allowing said damper cylinder unit to be horizontally adjustable with respect to said sleeve support member and sleeve member.
