Abstract: A metal piece having at least two areas of lower mechanical strength than the body of the piece, said pieces being respectively arranged on one side and the other of a longitudinal central section (PM) of said piece and alternatively located in two locations separated longitudinally along the piece, the areas of lower mechanical strength than the body of the piece being formed by local control of the stamping temperature during a stamping process of the piece, notably a process comprising steps including heating the piece to a temperature range suitable for obtaining an austenitic stage, then stamping this piece in a stamping tool suitable for defining different temperatures in the different areas of the stamped piece, for example by virtue of the voids formed in the stamping tool or by local reheating of the stamping tool.

Abstract: A riding lawn care vehicle (10) may include a frame, a steering assembly (30), a cutting deck (50) and a lifting assembly. Wheels (32,34) of the riding lawn care vehicle may be attachable to the frame. The steering assembly may be operably coupled to wheels of the riding lawn care vehicle to provide steering inputs to the wheels. The cutting deck may house at least one cutting blade and may be attachable to the frame. The cutting deck may include at least two cutting deck wheels (52) to facilitate level cutting responsive to operation of the at least one cutting blade when the cutting deck is in a cutting position in which the at least two cutting deck wheels contact the ground. The cutting deck may be liftable to an elevated position in which the at least two cutting deck wheels are not in contact with the ground.

Abstract: A vehicle door is manufactured by producing a supportive frame (10) and a waist rail (14) and a side impact guard beam (22) which are formed integrally with the supportive frame. The door is produced by hot stamping a steel sheet blank into the shape of a supportive door frame that includes an integral waist rail (14) and a side impact guard beam (22), and hardening the shaped door frame while the frame remains in the shaping tools, and fastening an outer panel (31) to the finished door such that the side collision guard beam (22) of the frame will lie close to the outer panel (31).

Abstract: Shock absorbing rectangular boxes (16, 17) are mounted between each one of two structural side beams (14, 15) of a vehicle and a bumper beam (11). The boxes are deep drawn from a steel sheet, and their sidewalls have deformation guides (35) so that the boxes are deformable in a controlled manner during a crash of the vehicle.

Abstract: A vehicle door has a supportive frame (10). A waist rail (14) and a side impact guard beam (22) are formed integrally with the supportive frame. The entire frame is made of high strength sheet steel. The door is produced by hot stamping a steel sheet blank into the shape of a supportive door frame that includes an integral waist rail (14) and a side impact guard beam (22), and hardening the shaped door frame while the frame remains in the shaping tools, and fastening an outer panel (31) to the finished door such that the side collision guard beam (22) of the frame will lie close to the outer panel (31).

Abstract: A supporting frame 10 of a door with an integrated side impact guard beam 22 is made of high strength steel. The outer panel 28 of the door will be close to the side impact guard beam. All the interior units of the door, such as lock and window structure 34–37 with window frame 37, are mounted on a beam structure 30. The beam structure is then mounted on the frame 10 so that the window structure will be between the frame 10 and the beam structure 30.

Abstract: A vehicle door has a supporting press formed frame (10) of high-strength steel that has two standing hat beams (13, 15) interconnected by an upper horizontal hat beam (14), a lower horizontal hat beam (16) and intermediate side impact guard beam (22). The hat beams have their crowns (12) directed towards the interior of the vehicle and they carry an outer panel (28) by their outer side flanges (17). The standing hat beams (13, 15) have a profile height on at least portion (23, 24, 28) of their length that overlaps the corresponding pillar (30, 34). Thereby, in a frontal crash, the frame of the door can transmit force from the A-pillar of the vehicle to the B-pillar.

Abstract: A vehicle door has a supporting frame (10) substantially in the form of a rectangular annular hat beam (13–16) of high-strength steel, which, with its outer side flange (17), carries the outer panel (28) of the door and has its crown (12) towards the vehicle interior. The lower rear portion of the outer side flange (17) has a bolt 32 arranged to fit in a hole (35) in the pillar (34). In case of a side impact, the bolt will make the pillar participate in the energy absorption. The frame (10) is comparatively shallow and it can therefore have a high yield strength and all the other elements of the door can be mounted on the inside of the frame, which make them easily available for service.
