A child car seat comprises a curvilinear frame. The frame includes right and left monolithic multilayered carbon fiber sidewalls each having a head retaining region and a bottom region connected by a central region. At least one beam connects one of the right and left monolithic multilayered carbon fiber sidewalls with the other. At least 20% of the surface area of each of the head retaining region and the bottom region is a hollow space. The right and left sidewalls are manufactured by placing carbon fibers and polymer to form a carbon fiber preform having a plurality of layers, each with a predefined orientation; and heating or curing the carbon fiber preform so that the polymer forms a matrix that binds the plurality of carbon fiber layers.

A seating device includes a headrest movably connected to a seat body. An adjustment mechanism is provided to adjust the position of the headrest relative to the seat body. An operating unit has a driving member to actuate the adjustment mechanism, and a handle portion bending from the driving member. The driving member is movable between non-operative and operative positions. In the non-operative position, the handle portion abuts against the headrest. In the operative position, the handle portion protrudes outward from the headrest.

A transportation system is disclosed. The transportation system includes a vehicle, a plurality of seating assemblies positioned within a passenger compartment of the vehicle and defining an arrangement, a plurality of actuators that effect movement of various components of the plurality of seating assemblies, a plurality of sensors, and a controller. Specific examples of pre-set or pre-programmed arrangements are disclosed, as well as the ability to customize the arrangement. Additionally, exemplary methods are disclosed that illustrate transitions between a variety of the pre-set or pre-programmed arrangements.

A side wing adjustment mechanism and an adjustable sitting device, the side wing adjustment mechanism includes: a pin arranged on the headrest; and an inclined grooves arranged on the side wing, a distance between a portion of the inclined grooves and the longitudinal center axis gradually decreases in a direction extending from bottom to top toward the headrest along a longitudinal center axis of the backrest, and the pin is slidable along the inclined grooves. According to the application, the side wing can be folded and opened at will, and the structure of the application is more inclusive. During the opening and folding process, puling of the headrest or pushing of the side wing can be performed more smoothly and labor-savingly, and the phenomenon of deflection and jamming can be avoided, such that the opening and folding process of the side wings is smoother.
