Abstract: According to an embodiment, a device for tightening an article includes a housing, a spool rotatably positioned within the housing, a knob operably coupled with the spool to cause the spool to rotate within the housing, and a stop mechanism. The device is configured so that incremental rotation of the knob in a first direction causes a corresponding incremental rotation of the spool within the housing that incrementally tensions a tension member and thereby tightens the article. The device is also configured so that incremental rotation of the knob in a second direction causes a corresponding incremental rotation of the spool that incrementally loosens the tension member's tension. The stop mechanism is configured to prevent rotation of the spool in the second direction when the tension member's tension achieves or falls below a tension threshold.

Abstract: A seat assembly for adjustably connecting a seat to a seat post is provided. The seat assembly may include a slider configured to slide along the seat post, a cam coupled to the slider and movable between a first position and a second position, and a cam washer positioned between the cam and the slider. The cam washer may include a base seated within a cutout disposed in the slider, the base having a non-circular shape for engagement with a complementary shape of the cutout. The cam washer may include a tab extending from the base, the tab seated within the cam. Associated systems and methods are also provided.

Abstract: A treadmill includes a deck having a continuous track, and a plurality of slats fixedly connected to the track. The treadmill also includes a first post extending from the deck, a second post extending from the deck opposite the first post, and a first arm supported by the first post and including a first rotary control. The treadmill further includes a second arm opposite the first arm and supported by the second post. The second arm includes a second rotary control separate from the first rotary control. The first rotary control is configured to control a first function of the treadmill and the second rotary control is configured to control a second function of the treadmill different from the first function.

Abstract: A seat assembly for adjustably connecting a seat to a seat post is provided. The seat assembly may include a slider configured to slide along the seat post and including an open end, a cam connected to the slider and movable between a first position and a second position, and a saddle shaft connected to the slider for connection with the seat. The first position may compress the open end of the slider to secure the slider to the seat post. The second position may allow the open end to expand to release the slider from the seat post and allow positioning of the slider along the seat post.

Abstract: A deck for a treadmill includes a continuous track, and a plurality of slats connected to the track. The track and the plurality of slats at least partly define an inner space of the deck, and are rotatable about the inner space. The deck also includes a first motor configured to modify a speed of rotation of the track, and a second motor configured to modify a position of the deck relative to a support surface on which the deck is supported. The first motor and the second motor are disposed within the inner space.

Abstract: In a preferred embodiment a friction bushing is configured to rotate a shaft with resistance having a housing with a bore to receive the shaft; a flange plate positioned on the housing around the bore; and a number of flanges that protrude axially from the flange plate to receive the shaft, where the flanges generate a radially-directed force by being flexible from a relaxed radius to a shaft radius of the shaft, and the flanges have internal circumferentially spaced surfaces in contact with an external surface of the shaft having a topology to control the resistance as the shaft rotates in the friction bushing.

Abstract: A friction bushing for being positioned on a shaft for friction-retarded rotation relative to the shaft, including a housing having a bore for receiving the shaft and a flange plate positioned on the housing around the bore. A plurality of flanges are carried by the flange plate and adapted for extending axially outwardly from the flange plate and along circumferentially-spaced apart areas of the shaft for frictionally-engaging axially-extending areas of the shaft.

Abstract: In a preferred embodiment, an aircraft passenger seat includes a seat back and a laterally-expanding tray table including a telescoping table segment and a main table segment having an interior pocket for receiving the telescoping table segment in a retracted position, where the telescoping table segment is adjacent to the main table segment in a fully extended position to form a contiguous table surface. The seat back may include a mounting region for stowing the laterally-expanding tray table, including a latching mechanism for latching the main table segment in a stowed position. The mounting region may extend across half the width of the seat back. The seat back may include storage region(s) horizontally adjacent to the mounting region, each storage region configured to stow a passenger convenience feature.
