Abstract: A passenger seat headrest may be provided for a passenger seat such as but not limited to an aircraft passenger seat. The passenger seat headrest includes a main portion, a wing, and a hinge connecting the wing with the main portion such that the wing is movable relative to the main portion about at least one axis. The hinge is adjustable such that a resistance to rotation of the wing relative to the main portion is adjustable.

Abstract: A central frame assembly for a passenger seat of a vehicle includes a spreader member (201) and a lower frame member (101) comprising at least one clamp member (121) for securing the lower frame member (101) relative to the spreader member (201). The lower frame member (101) may include a vertical portion (102) with a forward lower attachment portion (102.1) and an aft portion (103) with an aft lower attachment portion (103.1). The spreader member (201) and the lower frame member (101) may be aligned such that a centerline of the spreader member (201) and a centerline of the lower frame member (101) are approximately coplanar.

Abstract: An armrest assembly for a passenger seat includes a pivot member (101) attached to a seat frame (10), at least one armrest spine (102) attached to the pivot member (101), and at least one set screw (106) for adjusting a position of the pivot member relative to the seat frame. A pivot fastener (112) extends through a center hole of the pivot member (101) and through a first hole of the at least one armrest spine (102). A pin (110) extends through an arc slot of the pivot member (101) and through a second hole of the at least one armrest spine (102).

Abstract: Described are seat backs (102) for aircraft passenger seats (100). Such a seat back (102) can include a unitary structural core (112) formed as a single piece that includes a body (138) and a flange (140). The body (138) and the flange (140) can each include carbon fiber composite material. The flange (140) can include portions extending from the rearward-facing side (132) of the body respectively along a left lateral side edge, a top (134) side edge, and a right lateral side edge of the unitary structural core (112). The flange (140) can be non-tubular.

Abstract: Described are reclining passenger seats having deployable leg rests coupled to the seat bottom. An actuator, which may be a gas cylinder, spring, or electric motor, moves the deployable leg rest between stowed and deployed positions. A locking mechanism may be used to stabilize the deployable leg rest in the stowed position, the deployed position, or any intermediate position. The coupling of the deployable leg rest to the seat bottom allows for a greater range of movement with a lighter, more compact mechanism.

Abstract: Described is a passenger seat that includes a seat back with a lower portion disposed adjacent to the seat bottom, and recline mechanism configured to move the passenger seat between an upright position and a reclined position. The recline mechanism may move the passenger seat in two directions. The recline mechanism may include a plurality of corresponding members configured to interface with a plurality of elongate motion members.

Abstract: Described are passenger seats with a seat pan (12) releasably coupled to a seat frame (14) via at least one coupling device (20), which includes a ramp (22) mounted on a lower surface (36) of the seat pan (12) and a latch (42) pivotally coupled to an open end of the ramp (22). The latch (42) includes a flap configured to substantially cover the open end of the ramp (22) when the latch (42) is in a closed position, and a handle (48) that is accessible from an upper surface of the seat pan (12) via an aperture (50) in the seat pan (12). The coupling device also includes a spring (44) configured to position the latch (42) in the closed position until a force is applied to the handle (48) to rotate the latch (42) to an open position.

Abstract: A mechanical breather system for a four-stroke engine includes a rotating member. The rotating member can have at least one inlet channel in fluid communication between an outer perimeter of the rotating member and an inner region of the rotating member. A breather housing having an air receiving chamber formed therein is fluidly coupled to the at least one inlet channel of the rotating member. A passage can be formed through a wall of the breather housing is in fluid communication with the air receiving chamber and an exterior of the breather housing.

Abstract: Crankcase cover for sealing an opening in a crankcase the crankcase cover includes a body portion configured to be removeably coupled to the crankcase and a fluid level window. The fluid level window can have a flat portion with fluid level indicators thereon to signify the level of lubricant within the crankcase. The fluid level window is in fluid communication with fluid in the crankcase so that the fluid level within the crankcase can be seen through the fluid level window.

Abstract: A tool with an engine, a shaft, and a recoil starter pulley coupled to the shaft for rotation about an axis. A starter pull rope for winding and unwinding around the recoil starter pulley. An air chamber shroud extending about at least a portion of the pulley, the rope extending from the pulley through the shroud. A tube enclosing a portion of the rope and extending from a location adjacent to and aligned with the pulley to a location at an exterior of the shroud that is axially offset from the pulley. The tube may have flared ends to reduce gradual wear of the rope. The tube alters a trajectory of the pull rope to be substantially offset from the plane of the starter pulley so as to avoid interfering with neighboring structures inside the tool.
