Patent number: 7584037Abstract: An occupant determining device includes a load detecting sensor provided on a seat body and a controller. The controller calculates a detected load value based on an output value of the load detecting sensor and performs occupant determination based on the detected load value. The occupant determination state is switched to an adult determination state when a certain delaying time elapses after the detected load value exceeds a determination threshold. The controller sets plural determination thresholds, and the larger each determination threshold being exceeded by the detected load value is, the shorter the delaying time is set.Type: GrantFiled: July 17, 2003Date of Patent: September 1, 2009Assignee: Aisin Seiki Kabushiki KaishaInventors: Morio Sakai, Masaki Mori, Minoru Izawa, Yasunori Hasegawa, Daisuke Itoh, Norihiko Nagae

Patent number: 6987226Abstract: An occupant weight detecting apparatus for detecting an occupant weight on a seat includes a load sensor mounted on the seat to detect a load on the seat and output a load signal. A detected load value is calculated periodically based on the load signal and an average is calculated based on the detected load values calculated during a period in which the detected load value is less than a first predetermined. The average of the detected load values is set to a zero point, and the occupant weight is detected based on the detected load value and the zero point when the detected load value exceeds a second predetermined value.Type: GrantFiled: March 26, 2003Date of Patent: January 17, 2006Assignee: Aisin Seiki Kabushiki KaishaInventors: Morio Sakai, Koji Aoki, Masaki Mori, Minoru Izawa, Yasunori Hasegawa, Takaaki Enomoto
