Abstract: A juvenile seat includes a seat shell having a bottom seat portion and a back support portion coupled to the bottom seat portion and positioned at an angle relative to the bottom seat portion. A headrest of the juvenile seat is coupled to the seat shell and arranged for up and down movement relative to the seat shell above the bottom seat portion of the seat shell. The juvenile seat also includes a height-adjustment mechanism coupled to the headrest for up and down movement with the headrest to adjust the height of the headrest above the bottom seat portion.

Abstract: A juvenile seat includes a base and a lower back section coupled to the base. The base includes a bottom seat portion and the lower back section is positioned to lie at an angle relative to the bottom seat portion. The lower back section includes a planar front surface. A headrest of the juvenile seat is coupled to the lower back section for up and down movement relative to the base and the lower back section. The headrest includes a planar front surface and is positioned forward the planar front surface of the lower back section. The headrest and lower back section cooperate to provide a back rest surface for the juvenile seated therein.

Abstract: A juvenile vehicle seat assembly includes a seat having a side wall, an armrest mount coupled to the side wall of the seat, and an armrest coupled to the armrest mount for movement relative to the seat about a pivot axis between a raised position and a lowered position. The armrest mount includes an outer wall formed to define a first notch and a second notch spaced-apart from the first notch. The armrest includes an outer wall and a top wall coupled to the outer wall to cooperate with the outer wall to define a cavity formed to receive the outer wall of the armrest mount therein. A lug of the armrest is located within the first notch of the armrest mount in the raised position and is located within the second notch of the armrest mount in the lowered position.

Abstract: A juvenile restraint system includes a juvenile seat and a tether coupled at one end to the juvenile seat and at an opposite end to an anchor provided in a vehicle.

Abstract: A juvenile transportation system is provided which includes a seat shell detachably mountable on a small base wherein the small base is formed to be mounted on a vehicle seat with a seat belt. The small base is adapted to be mounted on a rear portion of a vehicle seat such that a portion of the seat shell lies on a forward portion of the vehicle seat when the seat shell is coupled with the small base. A large base can also be provided, the seat shell being adapted to be mounted on either the small base or the large base.

Abstract: A conveyor drive having a first crank (44) rotatably mounted to a base (24) for producing a first sinusoidal harmonic and a second crank (62) rotatably mounted to a conveying trough (22) for producing a second sinusoidal harmonic. A link (66) is connected between the first and second cranks (44, 62) to impart a first sinusoidal harmonic of the first crank (44) to the second crank (62). The second crank imparts a working displacement to the conveying trough (24) as a function of a phase relationship between the first and second sinusoidal harmonics of the respective eccentrics (44, 62). A synchronizer (FIG. 5) is operatively connected to the cranks (44, 62) for selectively adjusting the angular phase relationship between the first and second sinusoidal harmonics of the respective cranks (44, 62) to correspondingly vary the working displacement imparted to the trough (22), thereby controlling the speed of material being conveyed along the trough (22).
