  • Patent number: 9592755
    Abstract: The time until a headrest contacts the head of an occupant in the event of a rear collision is shortened with a simple configuration. In a seat device, a stay (46) (including grommets (22)) is set with bending rigidity towards the vehicle front lower than the bending rigidity towards the vehicle rear. Accordingly, when the headrest oscillates in the event of a vehicle rear collision, the headrest is initially displaced towards the vehicle rear, however the headrest changes direction in a short time and begins to be displaced towards the vehicle front. Moreover, there is a large displacement of the headrest towards the vehicle front since the stay (46) (including the grommets (22)) has a lower bending rigidity towards the vehicle front than the bending rigidity towards the vehicle rear. The time until the headrest contacts the head (H) of the occupant can accordingly be shortened.

  • Patent number: 8936310
    Abstract: A headrest including: a headrest body that supports a head portion of an occupant; a pair of side frame sections that supports the headrest body, the side frame sections extending along a seat height direction and disposed at a separation from each other along a seat width direction; and an inclined wall portion that is provided between the side frame sections, that is inclined towards a seat front-rear direction front side with respect to the side frame sections such that a lower end portion of the inclined wall portion is positioned further to the seat front-rear direction front side than an upper end portion of the inclined wall portion, and that bears load acting on the headrest body from a seat front-rear direction rear side.

  • Patent number: 8889722
    Abstract: An optically active 4-phenylthiazole derivative having a thrombopoietin receptor agonist activity and a pharmaceutical composition containing the present compound as an active ingredient are created, and a platelet production regulating agent which can be orally administered is provided. Disclosed is a pharmaceutical composition containing, as an active ingredient, an optically active compound represented by the formula: wherein, R1 is a halogen atom or C1-C3 alkyloxy; R2 is C1-C8 alkyl; R3 is C1-C8 alkyl; R4 and R5 are each independently a fluorine atom or chlorine atom; R6 is C1-C3 alkyl or C1-C3 alkyloxy; * indicates that a carbon atom marked with an asterisk is an asymmetric carbon, a pharmaceutically acceptable salt thereof, or a solvate thereof.

  • Publication number: 20140132048
    Abstract: In a seat device, a stay including grommets is set with bending rigidity towards the vehicle front lower than the bending rigidity towards the vehicle rear. Moreover, there is a large displacement of the headrest towards the vehicle front since the stay including the grommets has a lower bending rigidity towards the vehicle front than the bending rigidity towards the vehicle rear. The headrest can be promptly displaced towards the side of the head of the occupant due to setting the bending rigidity of the stay including the grommets, thereby enabling the time until the headrest contacts the head of the occupant to be shortened with a simple configuration.
