摘要： Recoil-reducing firearm including a compensating inertial mass coupled to the firearm by a flexible and resilient mass support, where the mass support permits translation of the compensating inertial mass along a translation axis but substantially prevents movement of the compensating inertial mass in a direction orthogonal to the translation axis. The mass support is configured so that movement of the compensating inertial mass in a distal direction can at least partially dissipate energy imparted to the firearm by firing a round of ammunition and impelling the projectile down the barrel.

摘要： A work vehicle includes a frame, an axle, a cab supported by the frame, a first tuned mass damper assembly, and a second tuned mass damper assembly. The frame includes a first longitudinal frame member and a second longitudinal frame member. The first longitudinal frame member has a first rear end, and the second longitudinal frame member has a second rear end. The second longitudinal frame member extends parallel to the first longitudinal frame member. The axle extends perpendicular to the first and second longitudinal frame members. The cab is disposed on a side of the first and second longitudinal frame members opposite the axle. The first tuned mass damper assembly is mounted on the first longitudinal frame member between the first rear end and the cab. The second tuned mass damper is mounted on the second longitudinal frame member between the second rear end and the cab.

摘要： Provided is a vehicle seat that facilitates setting of a starting load of a movable member. The vehicle seat includes a movable mechanism including: first and second springs coupled to a frame; a movable member displaceable relative to the frame; a first passive member and a second passive member coupled with the respective first and second springs; and a restriction member configured to restrict displacement of the first and second passive members. The movable member displaces the first passive member in a first direction when the movable member is displaced in the first direction, and displaces the second passive member in a second direction when the movable member is displaced in the second direction. The restriction member restricts displacement of the first passive member from a first-passive-member initial position in the second direction and displacement of the second passive member from a second-passive-member initial position in the first direction.
