Patent number: 7162344Abstract: An occupant detection system includes: a front weight sensor group formed from two weight sensors that are connected in series and arranged to the left and right on an upper face of a seat cushion; and a rear weight sensor group formed from two weight sensors that are connected in series and arranged to the left and right on the upper face of the seat cushion. The weight sensor groups are connected in parallel to each other. Regardless of whether an occupant sits on a front or rear part of a seat, since the load of the buttocks always acts on both left and right sides of the seat cushion, two series-connected left and right weight sensors of at least one of the plurality of weight sensor groups are both turned on without fail, thereby reliably detecting the occupant.Type: GrantFiled: November 12, 2004Date of Patent: January 9, 2007Assignee: Honda Motor Co., Ltd.Inventors: Mikihito Kojima, Masashi Yoshifuku, Toyohiko Shindo, Nobuhiro Koyota, Naotaka Kumakiri

Patent number: 7091426Abstract: In an occupant weight detection system, a pair of weight detection units are mounted along upper faces of base members fixed to a floor of an automobile. A square-frame-shaped linking member made of an iron sheet is interposed between the pair of weight detection units and a pair of seat rails. The pair of weight detection units are integrally linked by the linking member to maintain a positional relationship to each other at a predetermined relationship. Therefore, it is possible to prevent these weight detection means from being mounted in a state in which they are twisted or displaced relative to each other, thereby maintaining the detection accuracy.Type: GrantFiled: March 11, 2004Date of Patent: August 15, 2006Assignee: Honda Motor Co., Ltd.Inventors: Makoto Nagai, Mikihito Kojima

Patent number: 6928889Abstract: An occupant detection system, includes a sensor, a controller, a base frame, and a heat insulator. In this occupant detection system, the sensor measures a weight of an occupant sitting on the vehicle seat. The controller detects a presence of the occupant on the vehicle seat. The base frame is fixed to one of a vehicle seat or a vehicle body and accommodates the sensor. The heat insulator is provided on the base frame and prevents a heat transfer between the base frame and the sensor.Type: GrantFiled: August 8, 2003Date of Patent: August 16, 2005Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Mikihito Kojima, Kazutomo Isonaga, Harutomi Nishide, Nobuhiro Koyota, Yoshitaka Suzuki, Mitsugu Tosa, Makoto Nagai

Patent number: 6921108Abstract: Four load sensors having an upper limit value in a detection range are mounted in a seat of a vehicle. The weight of an occupant sitting on the seat is detected as a total of outputs from the load sensors. When the detected weight of the occupant is equal or larger than a predetermined value, the deployment of the air bag is permitted, and when the detected weight of the occupant is smaller than the predetermined value, the deployment of the air bag is prohibited. When any one of the outputs from the plurality of load sensors is the upper limit value in the detection range, the deployment of the air bag is permitted irrespective of the detected weight of the occupant. Thus, even when the output from the load sensor has been modified to the upper limit value by a limiting process, so that the weight of the occupant is calculated as a value smaller than an actual weight to become smaller than the predetermined value, the air bag can be deployed reliably to restrain the occupant.Type: GrantFiled: April 11, 2003Date of Patent: July 26, 2005Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Mikihito Kojima, Toyohiko Shindo, Makoto Nagai

Patent number: 6798196Abstract: A sliding seat position detection system includes a sensor provided on a seat that can slide on a floor of a vehicle, and a magnetic shielding member provided on the floor. The detection system detects that the seat is at a front end position when the shielding member provides a shield between a permanent magnet and a magnetism detection part of the sensor. A non-magnetic cover member is attached to the shielding member. When the seat is at a position other than the front end position, the cover member is positioned between the permanent magnet and the magnetism detection part of the sensor, thereby preventing erroneous detection due to magnetic foreign matter and other magnetic substances caught in or attached to the sensor.Type: GrantFiled: March 7, 2003Date of Patent: September 28, 2004Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Mikihito Kojima, Toyohiko Shindo, Makoto Nagai

Publication number: 20040145165Abstract: An air bag deployment control system, comprises a weight sensor which detects weight of an occupant sitting on a seat of a vehicle, and a controller which switches between deployment and non-deployment modes of an air bag based on the occupant weight detected by the weight sensor. The controller switches to the deployment mode permitting deployment of the air bag when the detected weight of the occupant is equal to or larger than a first threshold value, and switches to the non-deployment mode prohibiting deployment of the air bag when the detected weight of the occupant is smaller than a second threshold value. The second threshold value for switching from the deployment mode to the non-deployment mode is set smaller than the first threshold value for switching from the non-deployment mode to the deployment mode.Type: ApplicationFiled: July 7, 2003Publication date: July 29, 2004Applicant: Honda Giken Kogyo Kabushiki KaishaInventors: Makoto Nagai, Toyohiko Shindo, Mikihito Kojima
