  • Vehicle seat and stiffness setting method for vehicle seat
    Patent number: 10543764
    Abstract: A vehicle seat (1) includes a seat cushion (2) and a seat back (3), in which the seat cushion (2) is given a stiffness distribution in a front-rear direction in such a way that a front part of the seat cushion is provided with a low stiffness region (PSc) which is more flexible than a rear part of the seat cushion being a high stiffness region (PHc).
    Type: Grant
    Filed: September 30, 2011
    Date of Patent: January 28, 2020
    Assignee: NISSAN MOTOR CO., LTD.
    Inventors: Rumiko Oshima, Shigeki Ishiwata, Masahiro Egami, Akinari Hirao, Atsushi Takamatsu, Takayoshi Nagano, Mitsuhito Ito

  • Collision time estimation apparatus for vehicles, collision time estimation method for vehicles, collision alarm apparatus for vehicles, and collision alarm method for vehicles
    Patent number: 7262710
    Abstract: Imaging device picks up an image of the area around a vehicle, edge extraction function extracts an edge image from the image picked up by the imaging device, edge width standardization function standardizes an edge width of the edge image extracted by the edge extraction function, counting functions increments a count value corresponding to a position where the edge image standardized by the edge width standardization function is detected, and also initializes a count value corresponding to a position where the standardized edge image is not detected, moving speed detection function calculates a moving direction and moving speed of the edge image extracted by the edge extraction function based on the inclination of the count values, and collision time calculation function calculates the time of collision with an object by utilizing the position and the moving speed of the edge image calculated by the moving speed detection function.
