Patent number: 8915540Abstract: Provided is a vehicle upper structure which is capable of increasing, in a simple manner, a section modulus (resistive force) against a bending moment to be imposed on a roof reinforcement by a swinging phenomenon of a gusset occurring when a side impact load input into a center pillar and a roof side rail member is applied to the roof reinforcement from the gusset during a vehicle side impact event, to allow the load to be effectively dispersed to the roof reinforcement. The vehicle upper structure comprises a roof side rail member 4, a roof reinforcement 15 and a gusset 30, wherein an end of the gusset 30 on a side fastened to the roof reinforcement 15 has a shape which inclines with respect to a line L1 oriented in a vehicle front-rear direction, in top plan view.Type: GrantFiled: February 17, 2012Date of Patent: December 23, 2014Assignee: Mazda Motor CorporationInventors: Yoshikazu Nishimura, Tsuyoshi Kondo, Yasunari Futamura, Kazumi Shimizu, Kosuke Kojima, Seiji Nakano
