Patent number: 11479194Abstract: A vehicle front structure that absorbs a shock load applied to immediately under a front grille by using a structure at a position higher than a bumper beam as a support. The vehicle front structure includes a shock absorbing member at an interior of a bumper face below a front grille. The shock absorbing member includes a load receiving portion that receives a load, an abutting portion abutting against a structure above a bumper beam during receding of the shock absorbing member, an upper-side connecting portion connecting the load receiving portion and the abutting portion, a locking portion deformed while being locked to the bumper beam during receding of the shock absorbing member, and a lower-side connecting portion connecting the load receiving and locking portions. A bending facilitating portion extending in the vehicle width direction is formed on the side of a rear portion of the upper-side connecting portion.Type: GrantFiled: October 5, 2020Date of Patent: October 25, 2022Assignee: MAZDA MOTOR CORPORATIONInventors: Makoto Aizawa, Tetsuo Nagata, Ryosuke Kawafune, Yuta Mishima

Patent number: 11465688Abstract: A vehicle front structure that reduces a shock load applied to immediately under a front grille by using a bumper beam as a support. A vehicle front structure includes a shock absorbing member at an interior of a bumper face on the side near an upper portion thereof which absorbs a load from the diagonally upper front side. The shock absorbing member is at the interior of the bumper face below a front grille, and includes a load receiving portion that receives a load, a locking portion locked to an upper end edge of a bumper beam located behind and below the load receiving portion, at the time of receding of the shock absorbing member, and a connecting portion connecting the load receiving portion and the locking portion. A deformation facilitating portion with respect to a load from the upper front side is thus configured at the connecting portion.Type: GrantFiled: October 5, 2020Date of Patent: October 11, 2022Assignee: MAZDA MOTOR CORPORATIONInventors: Makoto Aizawa, Tetsuo Nagata, Ryosuke Kawafune, Yuta Mishima

Patent number: 11305711Abstract: An increased amount of absorption of a load from the diagonally upper front side is achieved even in, for example, a vehicle having a high vehicle height. A first shock absorbing member is provided inside a bumper face upper to absorb a load from the diagonally upper front side, a second shock absorbing member is mounted on a front face portion of a bumper beam, and a third shock absorbing member is disposed below the first shock absorbing member and between a bumper face and the bumper beam to absorb a load from the diagonally upper front side. The rigidity of the first and third shock absorbing members in the up-down direction is higher than rigidity of the second shock absorbing member in the front-rear direction.Type: GrantFiled: October 5, 2020Date of Patent: April 19, 2022Assignee: MAZDA MOTOR CORPORATIONInventors: Makoto Aizawa, Tetsuo Nagata, Ryosuke Kawafune, Yuta Mishima

Patent number: 4968530Abstract: The coating method includes the intercoating step for spraying the intercoating paint over a substrate after undercoating, the intercoat drying step for drying the intercoat on the substrate, the overcoating step for spraying the overcoating paint over the dried intercoat on the substrate, and the overcoat drying step for drying the overcoat. In the intercoating step, the intercoating paint is sprayed in such an amount as causing sag, that is, in an amount beyond its sagging threshold value. In the intercoat drying step, the substrate is rotated about its horizontal and longitudinal axis to dry the intercoat.Type: GrantFiled: March 8, 1990Date of Patent: November 6, 1990Assignee: Mazda Motor CorporationInventors: Takakazu Yamane, Yoshio Tanimoto, Tadamitsu Nakahama, Makoto Aizawa, Tsuneo Kishimoto
