  • Patent number: 11370572
    Abstract: A surface treatment method and a surface treatment device 2 for a resin vessel 1 forms a coating or performs surface modification on the surface of the resin vessel 1. In a sterilized environment as well as an environment with a pressure equal to or higher than the atmospheric pressure, a material for the coating or the surface modification is attached to at least one of an inner surface and an outer surface of the resin vessel 1, and the resin vessel 1, to which the material is attached, is irradiated with an electron beam to perform the coating or the surface modification. It is possible to form the coating or perform the surface modification on the resin vessel at a high speed.

  • Patent number: 8424965
    Abstract: A clutch mechanism in which a pressure receiving member is attached to two side frames of a seat back of a vehicle seat so as to be rotatable about rotation axes extending in a widthwise direction and in which when the pressure receiving member is rotated by a pressing load of an passenger sitting on the vehicle seat, the pressing load is selectively transmitted to an operation bracket pivotally connected to the rotation axes such that the operation bracket is rotated in the same direction as the pressure receiving member. When the pressure receiving member receives a quick pressing load, the operation bracket rotates while being mechanically integrated with the pressure receiving member, so that the pressing load can be transmitted to the operation bracket. When the pressure receiving member receives a slow pressing load, the operation bracket does not rotate, and only the pressure receiving member rotates, so that the transmission of the pressing load can be blocked.

  • Patent number: 8182014
    Abstract: With a vehicle seat arranging structure, a second-row passenger-side seat may be placed in a rearward slide position by sliding the second-row passenger-side seat toward the rear of a vehicle by 150 millimeters so that the second-row passenger-side seat is closer to the rear of the vehicle than the second-row driver-side seat. In addition, each of the second-row driver-side seat and the second-row passenger-side seat may be placed in an obliquely-inward frontward-oriented position by swiveling each of the second-row driver-side seat and the second-row passenger-side seat from the frontward-oriented position 10 degrees inward in the vehicle-width direction. In this way, the sense of distance between the occupants seated in the second-row driver-side seat and the second-row passenger-side seat is reduced. As a result, it is possible to promote communication between these occupants (to make it easier for these occupants to communicate with each other).

  • Patent number: 8078364
    Abstract: A vehicle seat apparatus includes: a vehicle seat; a swiveling drive unit that swivels the vehicle seat between the frontward-oriented position in which the vehicle seat faces the front of a vehicle and at least one of the outward-oriented position in which the vehicle seat is oriented in the outward direction of the vehicle and the inward-oriented position in which the vehicle seat is oriented in the inward direction of the vehicle; a traveling route information obtainment unit that obtains information on a traveling route along which the vehicle travels; and a control unit that controls the operation of the swiveling drive unit based on the information obtained by the traveling route information obtainment unit.

  • Patent number: 8047606
    Abstract: One aspect according to the invention can include a headrest operating device including a backside collision detecting device that can produce an operational force upon detection of occurrence of backside collision. The operational force of the backside collision detecting device can be transmitted to an operation member via an interlocking member. A switching device can switch a path of movement of the interlocking member between an inoperative path and an operative path. When no backside collision occurs, the interlocking member can move along the inoperative path, so that the operational force of the backside collision detecting device cannot be transmitted to the operation member. When the backside collision occurs, the interlocking member can move along the operative path, so that the operational force of the backside collision detecting device can be transmitted to the operation member.

  • Patent number: 7934763
    Abstract: A vehicle seat apparatus includes a vehicle seat; a swiveling drive unit that swivels the vehicle seat between a frontward-oriented position in which the vehicle seat faces the front of a vehicle and at least one of an outward-oriented position in which the vehicle seat is oriented in the outward direction of the vehicle and an inward-oriented position in which the vehicle seat is oriented in the inward direction of the vehicle; an occupant condition detection unit that detects the condition of an occupant in the vehicle; and a control unit that controls the swiveling drive unit based on the detection result obtained by the occupant condition detection unit. With this configuration, it is possible to further increase the comfort of a passenger compartment based on the condition of the occupants in the vehicle.

  • Publication number: 20100187874
    Abstract: A seatback includes an active headrest that moves forward to catch the back of the head of an occupant, when a load is applied by the occupant to a seatback in a rear-end collision. A first panel and a second panel are provided between a plurality of frame members that constitute the frame of the seatback. The first panel is flexible, and the second panel is more rigid than the first panel. A pressure-receiving member is attached to the second panel, receives the load applied by the occupant to the seatback through the second panel, and transmits the load applied to the seatback to a lock mechanism in the active headrest.
