The invention relates to a method for manufacturing hollow profiles, having the following method steps: providing an initial hollow profile which in an insertion wall and optionally in at least one intermediate wall displays an insertion opening, providing a support element which displays a bolt element, an engagement element, and support walls which are disposed between the bolt element and longitudinal flanks, passing through the support element through the insertion opening until the support walls are positioned in the initial hollow profile, engaging a tool on the engagement element, rotating the support element by means of the tool until regions of the longitudinal flanks touch inner walls of the initial hollow profile, connecting the regions of the longitudinal flanks to the initial hollow profile via the inner walls.

Method for manufacturing hollow profiles, and hollow profile

A hollow structure for installation as cross member or longitudinal member in a motor vehicle includes a hollow member which is made of light metal and has at least one hollow chamber. The hollow member has a wall which is formed with a slot. A flange sized to extend through the slot has a leg configured to rest by a formfit against a side of an inner surface area of the hollow member and at least one area which is coupled to an outer surface area of the hollow member.

Hollow structure with flange

A method for producing an energy-absorbing profile for a motor vehicle includes: providing an extruded hollow profile, the extruded hollow profile having outer walls and at least one inner wall which connects two of the outer walls; inserting a cutting tool into the hollow profile; actuating the cutting tool and cutting an inner wall section out of the inner wall; and removing the cut out wall section and the cutting tool from the hollow profile.
