  • Patent number: 11541788
    Abstract: A seat suspension includes a base including a base hook and a seat platform provided with a seat. A first link couples a first rotational axis of the base and a third rotational axis of the seat platform and is configured to be rotatable about the first rotational axis and the third rotational axis. A second link couples a second rotational axis of the base and a fourth rotational axis of the seat platform and is configured to be rotatable about the second rotational axis and the fourth rotational axis. A link hook is provided on the second link. An elastic member is latched to the base hook and the link hook and is configured to pull the link hook toward the base hook. A first angle between a contracting direction of the elastic member and a rotation direction of the link hook increases as the elastic member expands.

  • Patent number: 10328798
    Abstract: Work vehicle includes an operation lever pivoting forward and backward stepwise through a plurality of operation positions; and a detent type retention mechanism holding the operation lever in each of the operation positions. The retention mechanism includes a coupling member coupled to the operation lever; and a retention member holding the operation lever via the coupling member. The operation lever and the retention mechanism are provided separately from each other, aligned in a direction intersecting with a pivot support shaft of the operation lever. The operation lever and the coupling member are reciprocally connected via a linking mechanism.

  • Patent number: 9428048
    Abstract: The present invention includes a vehicle body frame. A cabin is mounted to the vehicle body frame so as to be isolated from vibration. A fuel tank is located below the cabin. The vehicle body frame includes a bracket extending laterally outward in a cantilever from at least one of a left side and a right side. The bracket includes: a cabin support portion carrying and supporting one front-back direction side of the cabin from below via a vibration isolation member; and a tank support portion supporting one front-back direction side of the fuel tank. The tank support portion is arranged at a position further toward an extended end than the cabin support portion of the bracket.

  • Patent number: 9352673
    Abstract: An armrest apparatus includes an armrest arranged on one lateral side of a driver seat. A height adjustment mechanism adjusts a height of the armrest relative to the driver seat. A flip-up mechanism swingably supports the armrest about a swing shaft center oriented in a lateral direction relative to the driver seat, whereby the armrest can be flipped up from a use position to a non-use position. The armrest apparatus also allows for height adjustment based on the physique of a driver and has an armrest that is movable to a position unlikely to interfere with boarding and unboarding.
