Patent number: 9061585Abstract: A cooling air introduction apparatus for a vehicle. A space that communicates with air introduction ports that are respectively formed in a bumper face of a front bumper and a front grille is partitioned by a vertical partition member. A space that communicates with the air introduction ports that are formed in the bumper face is partitioned by a horizontal partition member. Thus, streams of introduced cooling air are guided to heat exchangers without interfering with each other. The partition members are provided such that a bumper beam moves backward without any trouble upon a light collision.Type: GrantFiled: March 20, 2012Date of Patent: June 23, 2015Assignee: FUJI JUKOGYO KABUSHIKI KAISHAInventors: Yuji Fujiu, Yoshiyuki Shimizu, Atsushi Koizumi, Shiro Hasegawa
