A protecting member comprises a pair of right-and-left brackets extending obliquely downward and forward from front portions of a pair of right-and-left side frames and a stiffener extending in a vehicle width direction below a bumper beam and attached to front ends of the brackets. The stiffener has a closed cross section extending in the vehicle width direction, and an upper face of its central portion in the vehicle width direction has a concaved portion. A lower face of the stiffener extends horizontally substantially straightly. It is preferable that the closed cross section of the central portion of the stiffener be configured such that its vertical distance is relatively small and its longitudinal width is relatively large, compared with the other part of the stiffener.

Front vehicle-body structure of vehicle

A bumper reinforcement for a vehicle includes a front wall portion, a rear wall portion, a pair of vertically spaced connecting walls interposed between the front wall portion and the rear wall portion for establishing rigid connections therebetween, and a tow hook attachment member including a hollow body and at least one flange, the hollow body being penetrated through the front and rear wall portions, and the at least one flange being formed integrally with the hollow body to extend along an external surface of the rear wall portion, and secured to the external surface of the rear wall portion.

Bumper reinforcement for vehicle

Methods for manufacturing structures are provided. The methods include manufacturing a shell structure by additive manufacturing methods and sectioning panels with predetermined shapes from the shell structure. The panels are subsequently coupled to shell structure. Devices for performing various steps of the methods are also provided.

A rear vehicle body structure includes a rectangular frame, a box-shaped section, a spare-tire storage section, a peripheral flange, and a reinforcing member. The rectangular frame has a substantially rectangular shape in a plan view and includes left and right rear frames and front and rear cross members so as to contain a spare tire. The box-shaped section has a substantially rectangular bottom so as to be placed in the rectangular frame. The spare-tire storage section is provided in the box-shaped section and has an opening at an upper part of the box-shaped section to receive the spare tire. The peripheral flange projects outward from the upper part so as to be attached to the rectangular frame. The reinforcing member extends along the bottom in a front-rear direction of a vehicle body and is laid between the front and rear cross members.

Rear vehicle body structure

A bumper beam (11) is fastened in two crash boxes (12). The top part and bottom part of each crash box form fastening tabs (34,35) against the top and bottom of the bumper beam (11) and each tab is fastened to the bumper beam with more than one bolt (36,37,57 58). A first hole (55) fits a first bolt (57) whereas the other hole/holes (56) permit for the bumper beam to turn a limited amount around said first bolt. Each tab is fastened to the bumper beam with more than one bolt and nut fastener (36,37,57,58). A first hole (55) fits a first bolt (57) whereas the other hole/holes (56) permit for the bumper beam to turn a limited amount around said first bolt. If a crash box is compressed in an off-set crash, the other crash box remains intact.

A bumper beam mounting

The spare wheel recess (2) has an integrated hollow profile, which is molded by an injection process. The spare wheel recess is attached in a base structure of a vehicle by an angled flange (2.3). The base structure of the vehicle has a longitudinal support (5) and a lateral support (6). The hollow profile runs perpendicular to the longitudinal support and parallel to the lateral support. The spare wheel recess is designed as a plastic injection part.

Spare wheel recess for vehicle, has integrated hollow profile, which is molded by injection process, where base structure of vehicle has longitudinal support and lateral support

The deformable component (1) for a car is fitted into the recess (22) into which the spare wheel normally fits and absorbs energy in a rear-end crash. It has a circular outer wall and two parallel walls which extend across this and are arranged longitudinally along the car. An Independent claim is included for a method for increasing the resistance to deformation of a car using the component.

Deformable component is fitted into recess into which spare wheel normally fits and absorbs energy in rear-end crash

The structure has a C-column structure (2) with an upper C-column (3) and a lower C-column that is formed by an inner C-column (8) and an outer C-column (9). The inner and outer C-columns are arranged such that they are swivellable against each other with respect to their longitudinal axes. The upper and outer C-columns are connected with each other using a connection unit (10), which is connected with a roof frame (5). A support is arranged between the connection unit and a longitudinal chassis beam (13).

Motor vehicle body structure, has lower C-column formed by inner C-column and outer C-column that are arranged such that they are swivellable against each other with respect to their longitudinal axes

The towbar has towing loop (2) attached to a connecting bar (3) The bar has sections (4, 5) of different diameter, allowing it to be fitted into separate mountings at the front or at the rear of a vehicle

Towbar has towing loop attached to connecting bar which has sections of different diameter, allowing it to be fitted into separate mountings at front or at rear of vehicle

Air duct (19) has a shell structure-mounting part. Air duct also has two attachment points and a connecting element proceeds between the two attachment points. Air duct consists of two materials whereby the material of the shell structure-mounting part has a modulus of elasticity of 4000 M Pa between the two attachment points. An independent claim is included for the shell structure of a motor vehicle body.

Air duct for motor vehicle body, has shell structure-mounting part and two attachment points whereby connecting element proceeds between two attachment points
