  • Patent number: 8857870
    Abstract: A recess is formed at the center of a bumper absorber, provided on the vehicle outer side of a bumper reinforcement, so as to face forward, and an upper recess wall face of an upper absorber portion located on the upper side of the recess is inclined downward. If the subject vehicle is small in height and the amount of vertical overlap between the bumper absorber and the rear bumper of other vehicle (a barrier used in the narrow vertical overlap barrier test of the IIHS) is small, in the initial collision stage, the rear bumper of the other vehicle is guided by the inclined upper recess wall face to move relatively downward while the bumper of the subject vehicle moves relatively upward, preventing underride, increasing the amount of vertical overlap between the rear bumper of the other vehicle and the bumper absorber, and thus achieving reliable impact absorption.

  • Patent number: 7959229
    Abstract: A seat may be obtained with good operability of plural operating members for operating plural adjustable units. A vehicle seat is provided with: a seat lifter, provided to a seat body for sitting on and adjustable by operation force transmitted from a first operating system; a reclining mechanism, provided to the seat body and adjustable by operation force transmitted from a second operating system; and an operation force imparting unit that is provided at a position where it is able to be operated by a seat occupant at a predetermined position on the seat body. The operation force imparting unit is able to independently take up a first state in which a lifter knob is operated and the seat lifter adjusted, and a second state in which the reclining lever is operated and the reclining mechanism adjusted.

    Abstract: A seat may be obtained with improved operability of plural adjustable units. A vehicle seat 10 is provided with: a seat lifter 22 provided to a seat body that is for sitting on, and is adjusted by operation force transmitted from a first operating system; a reclining mechanism 20 provided to the seat body, that is adjusted by operation force transmitted from a second operating system; and an operation lever 30, imparting operation force for independently adjusting the reclining mechanism 20 and the seat lifter 22. The operation lever 30 imparts operation force to the seat lifter 22 when operated by rotation along the seat up-down direction in the direction of arrow D and arrow E, and imparts operation force to the reclining mechanism 20 when operated by rotation along the seat width direction in the direction of arrow F.

  • Patent number: 7731292
    Abstract: At a side portion 22 of a seat back frame, not only does a rear first extending portion 52 bend and extend from a frame side plate portion 30 toward a seat back inner side at an obtuse angle, but also, in a vicinity of a central portion of a rear flange portion 50, a rear second extending portion 54 bends and extends from the rear first extending portion 52 further toward the seat back inner side. Therefore, even if a relatively large load toward a rear of a vehicle acts on the seat back frame and compressive stress is generated at an intermediate portion of the rear flange portion 50 in a heightwise direction of a seat back, it is difficult for cross-sectional collapsing to arise, and the load can be effectively supported at the frame side plate portion 30. There can be provided a seat back frame for a vehicle which can suppress an amount of bending deformation at the time of a rear collision, without leading to an increase in weight.

  • Publication number: 20090158537
    Abstract: This static electricity and dust removing apparatus has a base box (11) provided with an airflow inlet port (16), and a processing head (23) attached to the base box (11) through a support column (21), wherein a processing space (24) is formed between the airflow inlet port (16) and the processing head (23). Air curtains for isolating the processing space (24) from the outside due to air from a spout of an air spout pipe (33) are formed at a front opening portion (29) and right and left side opening portions (28) of the apparatus. Ionized air generated by an ion generator (42) is spouted into the processing space (24), so that the ionized air is sprayed on matters to be processed which are disposed in the processing space (24) and dust is removed from the matters to be processed.
