Arrangements for safety and comfort in vehicles.

A child seat including a tensioning mechanism for applying tension to a seat belt to more fully secure the child seat to a vehicle seat is provided herein. The child seat, which may be front- and/or rear-facing, includes a seat base defining a seat portion and a backrest portion. The seat base can receive an untensioned belt to secure the child seat to a vehicle seat in an untensioned configuration. A tensioning mechanism attached to the backrest portion and is rotatable between a first position substantially adjacent to the backrest portion and a second position disposed therefrom. In the second position, the tensioning mechanism can receive a portion of the belt. In the first position, the tensioning mechanism applies tension to the portion of the received belt to secure the child seat to the vehicle seat in a tensioned configuration. Methods of manufacturing child seats are also provided herein.

A child's booster seat with detachable belt positioner car seat is provided. The booster seat can include a seat back that can be coupled and decoupled from a seat base. The seat base can include a primary seat base and a removable seat base. The removable seat base can be coupled and decoupled from the primary seat base and used as a booster seat for a child without the primary seat base. The primary seat base can include protrusions and/or recesses and the removable seat base can include recesses and/or bosses for aligning and/or coupling the removable seat base to the primary seat base. A pair of armrests can be adjustably coupled to the seat base, such as to the removable seat base. The seat base can further include one or more lap belt positioners. The seat back can include an adjustable headrest and one or more shoulder belt positioners.

An infant restraint system includes: a back rest portion; a seat portion connected to a lower portion of the back rest portion swingably between an in-use and storage position; upper side position regulating portions formed on a left and right portion of an upper portion of the back rest surface; lower side position regulating portions formed on a left portion and a right portion of the back rest surface at a position below the upper side position regulating portions; an upper body belt portion which includes the pair of shoulder belts and a pair of tongue plates attached to the pair of shoulder belts; a side guard portion respectively extending frontward from a left edge portion and a right edge portion of a lower portion of the back rest portion; and a crotch belt portion having a buckle body which is detachably engaged with the pair of tongue plates.

Seat assemblies are provided which include a seat base structure, a seat cushion supported by the seat base structure and at least a lateral outboard seat lip positioned relative to the seat cushion so as to assist a passenger during seat entry and exit. The lateral outboard seat lip is preferably attached relative to the seat cushion for manual movements between an extended position wherein the outboard seat lip extends outwardly thereby increasing effective surface area of the seat cushion and a deflected position wherein the outboard seat lip extends upwardly or downwardly relative to the seat cushion so as to thereby decrease the effective surface area of the seat cushion.

A child restraint system includes a shell including an aperture formed therein. The child restraint system further includes a head support member disposed with at least a portion of the shell. The child restraint system further includes a bumper configured to extend through the aperture and contact a part of the head support member when a force is applied to the bumper.

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.

An infant carrier includes a seat body, a storage unit and a non-rigid restraint assembly. The seat body is shaped to support an infant. The storage unit is integrated into the seat body, and the non-rigid restraint assembly is secured to the storage unit. The storage unit is configured to retain an entirety of the non-rigid restraint assembly therein.

An actuator for a vehicle seat can be configured to prevent overstress of a shape memory alloy (SMA) wire. The actuator can include a first body member and a second body member pivotably connected to each other. The actuator can include an overstress post and an overstress contact plate operatively connected to the overstress post. Thus, movement of the overstress post causes movement of the overstress contact plate. The actuator can include an overstress contact pin. The actuator can include an SMA wire operatively connected to one of the body members and to the overstress post. When activated, the SMA wire can shrink, causing one of the body members to pivot relative to the other body member and causing the overstress contact plate to move toward the overstress contact pin. If the overstress contact plate contacts the overstress contact pin, the SMA wire can be deactivated.

A newborn insert for a child safety seat may include an accommodation region for a child, and an energy-transferring element. The energy-transferring element may include an inherently stable component, and may be arranged laterally at the accommodation region such that the energy-transferring element is positioned at the child's shoulder height when the child is placed in the accommodation region.
