Abstract: A vehicle bumper beam attachment structure includes a shock-absorbing extension member through which a bumper beam is attached to a vehicle body. The extension member is formed from an aluminum extruded hollow profile and includes a rear wall for abutment with the vehicle body, an inner sidewall extending convexly from an inner end the rear wall toward the bumper beam, a central sidewall extending from a central portion of the rear wall in substantially the same direction as the inner sidewall, a first front wall connecting distal ends of the inner and central sidewalls, a branched sidewall branched off from the central sidewall and extending convexly toward the bumper beam, an outer sidewall extending from an outer end of the rear wall toward the bumper beam, and a second front wall connecting distal ends of the branched and outer sidewalls.

Abstract: A guard assembly for a snowmobile having two forwardly extending skis includes a first support mountable to a first ski and a second support mountable to a second ski. A slide assembly is mounted to and between the first and second supports. The slide assembly includes a first slide member joined to the first support and a second slide member joined to the second support. The first slide member moves relative to the second slide member during operation of the snowmobile.
