摘要:
The invention relates to a locking fluid spring comprising a piston (20) movable in a cylinder (1) containing a fluid (14) so that movement of the piston varies the pressure of the fluid, a first flow path (10) between opposite sides of the piston, controlled by a valve (11) operable externally of the cylinder, the valve (11) being movable in the first flow path between a locked position of the spring preventing flow of the fluid from one side of the piston to the other and an unlocked position allowing controlled flow of fluid through the first flow path, a relief flow path (30), a closure member (22) urged by spring biasing means (25) to a normally closed position closing the relief path, the arrangement being such that excess pressure on one side of the piston will act to move the closure member to an open position in which fluid can flow to relieve the excess pressure and allow movement of the piston in the cylinder while the valve remains in its locked position. The biassing means acts to reset the locked spring immediately an overload is removed. Preferably the first flow path (10) is through the centre of the piston and the relief flow path (3) is also through the piston. Preferably the closure member comprises an outer annulus (22) of the piston (20) slidable axially relative to a central portion (21) of the piston.

This invention relates to a recline-locking apparatus for a passenger's seat in which shoulder harness (12) is provided on a seat back (1) for a vehicle, a ship or an aircraft. In a base frame (5), a pair of left and right spreaders (6) are formed each of which is provided with a front support (6a) extending substantially horizontally between front and rear beams (3, 4), and a rear support (6b) projecting from the rear portion of the front support (6a) so as to be inclined in the rearward upward direction, a seat back frame (2) being supported pivotably at its lower end portion on the rear support (6b) of the spreader (6), a bearing being formed on the portion of the seat back frame (2) which is on the upper side of a pivotably supported portion thereof with respect to the rear support (6b) of the spreader (6), and which is on the side of the base frame (5), an arm (13) being fixed to the rear end portion of the front support (6a) of the spreader (6), a guide bore (14) opposed to the bearing formed on the seat back frame (2) being made in the upper portion of the arm (13), a buffer structure (16) being formed in the guide bore (14), a lower end portion (15b) of a lock bar (15) fixed pivotably at its upper end portion to the bearing (2b) of the seat back frame (2) being fitted firmly in the guide bore (14) via the buffer structure (16) so that the lower end portion (15b) of the lock bar (15) can be moved slidingly in the axial direction in the guide bore (14) in the arm (13) in accordance with a reclining movement of the seat back frame (2), an impact load of not lower than a predetermined level imparted to the seat back (1) due to the loss of mechanical energy occurring when the buffer structure (16) is deformed or buckled being damped and absorbed.

Betätigungsvorrichtung für Verstellmechanismen von Sitzmöbeln, wobei mittels eines Kraftübertragungselements ein Mechanismus eines Sitzmöbels gegen die Kraft eines Federelements betätigt wird und das Kraftübertragungselement ein Bowdenzug, bestehend aus einem Draht (8) und einer diesen umgebenden Metallspirale (10) ist, wobei der Draht (8) des Bowdenzugs an seiner einen Seite mit einem Betätigungshebel (2) und an seiner anderen Seite mit einem Auslöser (20) für das Federelement verbunden ist.
摘要:
The stroke length in a positioner (10) of the type having a piston rod (14) movable through a cylinder (12) can be preset through a continuous range of adjustment. A first detent element (22) provided at the end of the cylinder engages another detent element (66) positionable along the rod to limit stroke length. Spacing between the two detents is continuously adjustable by rotatation of a threaded sleeve (50) coaxial with the rod. Once installed in a recliner seat or the like, the device is secure against accidental changes in the stroke setting.
