Patent number: 6422632Abstract: As a moveable part of the vehicle body carrying a vehicle seat moves rearward under the action of an active or passive power source as a result of a vehicle crash, the seat belt which is anchored at the moveable part at one end and a fixed part of the vehicle body at another end is pulled rearward, and performs the function to apply a deceleration to the vehicle occupant in an early phase of the vehicle crash. This is followed by a slight slackening of the seat belt as the moveable part is subjected to a forward force. The active power source typically consists of a high pressure gas generating device, and a passive power source typically consists of a G control member which transmits the deceleration of a vehicle crash to the vehicle occupant from an early phase of the crash, and/or a stopper which applies a forward force to the moveable part as the moveable part moves rearward by a prescribed distance under the action of the power source.Type: GrantFiled: August 23, 2000Date of Patent: July 23, 2002Assignee: Honda Giken Kogyo Kabushi KaishaInventors: Takahiro Kamei, Tatsuo Iwabe, Yasushi Kawamura, Makoto Tsuruta, Yasuki Motozawa, Kazuya Yoshida

Publication number: 20020084131Abstract: A lock plate and a movable plate are provided to fix a seat at an optional position, and an actuator is provided between the seat and the movable plate. The seat is moved to the rear of a vehicle body in an initial stage of impact by the actuator. Acceleration is generated in the seat through impact abutment of a collapsible tube in the actuator against a piston head in an intermediate stage of impact. In a final stage of the impact, the seat is made integral with the vehicle body. The deceleration of a vehicle body and a seat and the deceleration of an occupant can be made equal to each other at an earlier timing. The apparatus can be installed by making use of a space under the seat, whereby the necessity of securing a special vacant space for installation of the apparatus can be obviated.Type: ApplicationFiled: October 30, 2001Publication date: July 4, 2002Applicant: HONDA GIKEN KOGYO KABUSHIKI KAISHAInventors: Yasuki Motozawa, Takahiro Kamei, Yasushi Kawamura

Patent number: 6402218Abstract: Provided is a seat belt pretensioner device for a seat belt having a plurality of anchor points attached to different parts of a vehicle body which includes a G control vehicle body member which deforms in a different pattern from a remaining part of the vehicle body at the time of a vehicle crash. One of the anchor points, which typically consists of a seat belt buckle, is attached to the G control vehicle body member via a force transmitting member such as a cable member which is adapted to move the anchor point in a direction to increase a tension of the seat belt at the time of a vehicle crash. A seat belt pretensioner device can be thus achieved in a simple manner without requiring any special power actuator.Type: GrantFiled: July 21, 2000Date of Patent: June 11, 2002Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Takahiro Kamei, Tatsuo Iwabe, Yasushi Kawamura, Makoto Tsuruta, Yasuki Motozawa, Kazuya Yoshida

Patent number: 6394535Abstract: The vehicle occupant protection system can significantly reduce the peak deceleration of the vehicle occupant even with a small vehicle body. The system comprises a seat supported on a vehicle body so as to be slidable in a direction of an input crash load resulting from a vehicle crash; a first member connected to the seat and adapted to deform under the crash load upon occurrence of a vehicle crash; a second member connected to a main part of the vehicle body and adapted to deform under the crash load; and a power actuator for applying a forward force to the seat relative to the vehicle body with a certain time delay after the occurrence of the vehicle crash; the first member being adapted to substantially deform only after the forward force is applied to the seat upon occurrence of a vehicle crash.Type: GrantFiled: June 30, 2000Date of Patent: May 28, 2002Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Yasushi Kawamura, Takahiro Kamei

Patent number: 6312038Abstract: In an automotive vehicle body structure comprising a seat carrying member that is moveable with respect to the main part of the vehicle body at the time of a vehicle crash so as to reduce the peak deceleration of the vehicle occupant in the seat, the seat carrying member comprises an elongated member extending in a fore-and-aft direction of the vehicle body and having a portion adapted to be deformable at the time of a vehicle crash. The seat is preferably connected to the elongated member of the seat carrying member at a widthwise center of the seat so that at the time of a vehicle crash, the inertial force of the seat and the vehicle occupant will act in the direction that the elongated member extends and substantially no horizontal moment will be applied on the seat carrying member. A seat position adjustment mechanism is preferably provided between the seat and the elongated member of the seat carrying member.Type: GrantFiled: July 21, 2000Date of Patent: November 6, 2001Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Yasushi Kawamura, Tatsuo Iwabe, Takahiro Kamei, Makoto Tsuruta, Yasuki Motozawa, Kazuya Yoshida

Patent number: 6254164Abstract: In a vehicle occupant protection system, the seat is subjected to a forward deceleration by a power actuator following a frontal vehicle crash substantially without any time delay, and following a rearward movement of the seat with respect to the vehicle body by a prescribed distance, the seat is subjected to a forward acceleration by a stopper attached to a vehicle body to prevent any excessive rise in the forward deceleration of the vehicle occupant. Thereafter, the vehicle seat is required to move substantially integrally with the vehicle body to allow the vehicle occupant to decelerate at a tolerable deceleration level by virtue of a controlled deformation of the vehicle body, and the one-way motion mechanism ensures the vehicle seat to move jointly with the vehicle body once the stopper has stopped the rearward movement of the seat.Type: GrantFiled: July 28, 2000Date of Patent: July 3, 2001Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Yasushi Kawamura, Takahiro Kamei

Patent number: 5795374Abstract: A coating composition comprising a rosin compound, a polymer containing organosilyl ester groups, and an antifoulant as essential components is disclosed. This rosin-based coating composition gives a coating film which forms no residue layer on the surface thereof over long-term immersion, is hence free from physical defects such as cracks and peeling and capable of maintaining a sufficiently high rate of film erosion and preventing the attachment of marine organisms over a long period of time has satisfactory suitability for recoating, and has the satisfactory ability to prevent marine-organism attachment over the out-fitting period.Type: GrantFiled: April 15, 1997Date of Patent: August 18, 1998Assignee: NOF CorporationInventors: Masayasu Itoh, Shigeo Fukuda, Yoshihisa Kawakami, Yoshiro Matsubara, Yasushi Kawamura, Shigeru Masuoka, Yoshihiro Honda
