Abstract

A vacuum brake force booster for a vehicle brake system, in particular, with a master brake cylinder that can be attached along with the brake force booster to a wall of an automotive vehicle, with a housing comprised of at least two wall elements attached to each other, and with at least one reinforcing element that extends through the interior of the housing and has a thin-walled tubular shape. The essence of the present invention is that the reinforcing element on at least one end passes over into a radially extending fastening portion which extends, at least in a partial zone, in parallel to the associated wall element and is supported on the wall element so that the interior of the brake force booster is separated pressure-tightly from the atmosphere. The present invention permits a simple and low-cost assembly of the brake force booster without the necessity of additional sealing elements which are difficult to mount.
