  • Patent number: 11440448
    Abstract: There are improved a vibration absorption characteristic and an impact absorption characteristic. In a suspension mechanism 1 of the present invention, first and second dampers (150, 160) are suspended in parallel between an upper frame (120) and a lower frame (110) with mounting angles different from each other. For this reason, the smaller mounting angle the damper has, the smaller a vertical component of damping force becomes, and the damping force which acts on the upper frame (120) and the lower frame (110) which move up and down relatively is moderate in effectiveness as compared with a case of disposing all the dampers at the same mounting angle. Thus, a sense of incongruity in which strong damping force acts abruptly is suppressed and the vibration absorption characteristic and the impact absorption characteristic are improved, which leads to improvement in ride comfort.

  • Publication number: 20220234482
    Abstract: The operation in a closing direction and the operation in an opening direction of a storage rack are performed efficiently with small force. Fixed frames and a storage rack are connected by link mechanisms, and the link mechanism includes fixed-side links linked to the fixed frame and movable-side links linked to the storage rack. When a position of one ends of the movable-side links is located closer to one ends of the fixed-side links than a balanced point, the elastic member biases the storage rack in an open-position direction. In the open position, since the elastic member biases the storage rack in the opening direction, an open state is maintained as long as the position of the one ends of the movable-side links does not return to the change point position. Accordingly, the open position can be held by a simple structure without using electric power.

  • Publication number: 20220228637
    Abstract: To cause an appropriate damping force to work according to a relative displacement with a simple configuration. A movable inner cylinder 3 slidable in an outer cylinder 2 in an axial direction and having orifices 31 formed in its peripheral wall 31 is provided, a piston 5 around which a linear member 52 that generates a frictional force is wound is further provided in the movable inner cylinder 3, and a viscous liquid 7 is filled in the outer cylinder 2 including the inside of the movable inner cylinder 3. Accordingly, when the piston 5 moves together with the movable inner cylinder 3, a high damping force is not exerted, whereas when the piston 5 relatively moves in the movable inner cylinder 3, the high damping force is exerted owing to viscous friction between the piston 5 and the movable inner cylinder 3 and the viscous resistance of the viscous liquid passing through the orifices.

  • Patent number: 9862291
    Abstract: A seat slide device includes lower rails and upper rails both formed substantially symmetrical bilaterally across a center in a width direction, and lock mechanisms on both sides of the upper rails to be engaged with the lower rails to lock them. An entire structure combining the lower rails, the upper rails and the lock mechanisms is substantially symmetrical forward, backward, and bilaterally, and a force applied to the lower rails and the upper rails can be absorbed substantially evenly forward, backward, and left and right. Since the lock mechanisms have an elastic lock member in a substantially center part in a longitudinal direction, the lower rails and the upper rails are elastically deformable for reduction of a biased load at a time of locking, improvement in vibration absorption characteristic, and the like, and a plate thickness of each material can be made thinner than conventional for weight reduction.

  • Patent number: 9840170
    Abstract: A seat suitable for sports type automobiles with a low hip point. An energy absorbing structure part provided in a cushion frame is constituted of a substantially square frame body including a front beam and a rear beam, and stringers bridged across them and provided separately from side frames. It is structured such that belt anchor attaching members are each provided between a coupling position to a vicinity of a rear portion of upper rails of sliders and a coupling position of the rear beam in the stringers. When an impact force of a predetermined value or higher is applied, the stringers deform to absorb the impact force and trusses are formed after the deformation, thereby enabling to sustain a further impact force which continues to be applied.

  • Patent number: 9738196
    Abstract: A base net for a back is formed from a three-dimensional stereoscopic knit, and has a configuration in which seams for bringing a pair of ground knitted fabrics thereof to close to each other in a thickness direction are partially provided, predetermined preliminary compression is applied in the thickness direction by the seams, and thereby residual stress is generated in a surface direction (stretching direction). Therefore, stiffness is partially increased by partial improvement in residual stress, and consequently a human body with extreme roughness is supported by nearly uniform pressure. Thus, in spite of a simple configuration in which the seams are provided in desired regions, posture supportiveness and body pressure dispersiveness can be improved. Further, by arbitrarily adjusting the formation positions of the seams, the pressure distribution is adjusted, thereby making it possible to easily control the vibration mode to desired setting, and easily improve vibration absorbency.

  • Patent number: 9522448
    Abstract: A predetermined component such as a recliner is attached to a long member in advance, and thereafter by bending the long member, a pair of side frames and an upper frame are integrally formed. Therefore, the recliner can be attached to the long member not bent yet and thus in a substantially flat state, and in addition, the pair of side frames and the upper frame can be integrally formed, which does not require labor and contributes to a reduction in manufacturing cost. Moreover, by adjusting a position where the bending is performed, it is possible to manufacture seat frame structures different in dimension even if the long members not bent yet have the same length, and from this viewpoint as well, it is possible to reduce labor and manufacturing cost.
