A bearer, especially a longitudinal bearer of a motor vehicle frame, which is constructed as hollow profile and includes a deformable section dissipating impact energy; the walls of the longitudinal bearer have different strength characteristics as a result of a treatment of these areas changing the strength of the wall material compared to non-treated areas; a greater strength thereby exists in the treated wall areas than in the untreated areas.

Hollow bearer for vehicles and method for its manufacture

A flank protection for the protection of passengers from impacts of lateral areas of motor vehicles comprises a vehicle body side wall having a window, such as a door, wherein reinforcement for preventing excessive penetration of the vehicle by other vehicles is located solely in lower areas of the side wall, particularly in an outer body part, while an upper side wall portion is formed of inner and outer body parts, preferably above a belt line of the vehicle, are composed of resilient portions that are yieldable to the absorption of outwardly directed reaction forces applied by an occupant against said body parts above said belt line.

Lateral protection of motor vehicles

An anchoring arrangement of an end point or deflection point of a safety belt, especially in motor vehicles, under interposition of a spring at a fixed vehicle part; the spring is installed prestressed in the sense of a tightening of the belt band and is blocked in the normal driving operation in this position while the blocking is released by a force peak exceeding the prestress force of the spring which occurs at the beginning of an accident at the belt band.

Hollow bearer for vehicles

A longitudinal bearer constructed as hollow profile of a motor vehicle frame, which is equipped with introduction places for introducing chassis forces into the frame and into the longitudinal bearer and with a longitudinal deformable bearer section arranged outside of the introduction places and dissipating impact energy; the longitudinal bearer section which by reason of different wall thicknesses has a resistance to buckling that increases in the direction toward the vehicle center, is transversely subdivided over its length at least into two bearer pieces connected with each other by circumferential seams; the wall thickness of a respective bearer piece becomes greater and/or the wall quality thereof becomes better in the direction toward the vehicle center from bearer piece to bearer piece than the wall thickness and/or the wall quality of the bearer piece disposed in front thereof.

Longitudinal bearer and method of constructing same

A longitudinal bearer of a motor vehicle frame, constructed as hollow profile which is provided with places for the introduction of chassis forces into the frame and into the longitudinal bearer and which includes a longitudinal bearer section arranged outside of the introduction places and dissipating deformable impact energy; this longitudinal bearer section, by reason of a differing wall thickness progress, has a resistance to buckling that increases in the direction toward the vehicle center; to that end at least the longitudinal bearer section located outside of the force introduction places is longitudinally subdivided over its length at least into two bearer parts consisting of sheet-metal profile members which are connected with each other along longitudinal seams, whereby the sheet-metal members have different wall thickness while the longitudinal seams extend obliquely to the longitudinal axis of the longitudinal bearer section such that the sheet-metal bearer member with greater wall thickness has a greater share in the circumference of the longitudinal bearer section in areas thereof located nearer the vehicle center than in areas thereof located nearer the end of the vehicle.

Longitudinal bearer

A lateral protection for motor vehicles in which at least one reinforcement extending essentially in the vehicle longitudinal direction is arranged on the inside of each door, whereby in case of an external force influence or action which occurs in the vehicle longitudinal direction the reinforcements, preferably constructed as hollow bearers, are supported in the vehicle longitudinal direction with one end each either directly or indirectly at a fixed structural part such as, for example, at an upright column or at a wheel casing or at a further reinforcement belonging to an adjacent door.
