Title: Structure of vehicle side
Inventor: IMADA MITSUHIKO
IPC: B62D25/06
Filed: 2020-11-11
Abstract: To provide a coupling structure of the upper part of a center pillar of a vehicle in efficiently conducting the transmission of a load.SOLUTION: An upper part of a center pillar outer reinforcement 40 and a top wall 3602 of a center pillar inner reinforcement 36 posing a hat shape are coupled to a roof rail outer reinforcement 28 at the same coupling point P. Accordingly, when a load F from diagonally above vehicle side is applied to a roof rail 12 during roof crush, the load shown by an arrow is distributed for transmission to two members of the center pillar outer reinforcement 40 and the center pillar outer reinforcement 36 through the same coupling point P. Compared to when the load F is transmitted to only the center pillar outer reinforcement 40, the transmission of the load is performed more efficiently. Even when a vehicle body 10 with a large weight is rolled, it is more advantageous in suppressing the center pillar 16 from being deformed along with the roof rail 12.SELECTED DRAWING: Figure 6
