A car seat configured to be fastened to a vehicle, includes a seat shell and a belt guide disposed at the seat shell to redirect a belt set of the vehicle for rerouting the belt set along a deviation path from an original path. When the belt set is not engaged with the belt guide, the belt set is routed along the original path. When the belt set is engaged with the belt guide, the belt set is routed along the deviation path from the original path. The rerouted belt set improves the symmetry of forces encountered by the vehicle and also improves the kinetics of the car seat during a crash. A break-away feature in the belt guide advantageously absorbs forces at different times during a crash.

The invention relates to a child seat for attaching to a motor vehicle seat, comprising a seat region, a backrest, a headrest having at least one belt guide, and a headrest inclination adjustment device for adjusting an inclination of the headrest relative to the backrest.

The present application describes a system and method for converting a natural language query to a standard query using a sequence-to-sequence neural network. As described herein, when a natural language query is receive, the natural language query is converted to a standard query using a sequence-to-sequence model. In some cases, the sequence-to-sequence model is associated with an attention layer. A search using the standard query is performed and various documents may be returned. The documents that result from the search are scored based, at least in part, on a determined conditional entropy of the document. The conditional entropy is determined using the natural language query and the document.

A support base for a child safety seat includes a shell, a belt clamp and a latching mechanism. The shell is adapted to receive a child seat thereon, and has a panel at an end thereof and a belt anchoring region adjacent to the panel, the belt anchoring region including a first and a second surface, the second surface being supported by the panel and connected with the first surface. The belt clamp is pivotally connected with the shell, and is operable to clamp a first and a second belt portion respectively adjacent to the first and second surface. The latching mechanism is operable to lock the belt clamp in a clamping state.

An insert for repositioning at least one of the harness straps of a child safety seat in order to accommodate an occupant smaller than the harness is configured to accommodate, wherein the insert is adapted to locate between the child safety seat and the occupant and includes a pair of waist strap guides, each waist strap guide configured to allow a waist strap of the harness to extend through and exit the waist strap guide at a position narrower than where the waist strap exits the child safety seat.

A child safety seat includes a support base, a rotary platform and a child seat. The support base is suitable for placement on a vehicle seat and includes an anchoring portion and a bearing portion connected with each other, the anchoring portion having a belt path for passage of a fastening belt to attach the child safety seat on a vehicle seat. The rotary platform is pivotally connected with the bearing portion of the support base about a pivot axis. The child seat is connected with the rotary platform, wherein the child seat, the rotary platform and the bearing portion are movable in unison relative to the anchoring portion, and the child seat and the rotary platform are rotatable in unison as a seat unit relative to the support base between a plurality of positions including a forward facing position, a rearward facing position and a sideways facing position.

A device and system that can be used to assist actuation of a buckle release is disclosed. A device can comprise a first arm and a second arm joined by a U-shaped connecting portion. The device can also comprise a button contact feature. The device can be inserted over a buckle with the button contact feature over a buckle release button, and the device used to assist engagement of the buckle release button by a person operating the device. A system can comprise a device and various additional features or accessories.

A buckle fastening assembly is adapted for a child safety seat and includes a cushion body whereon a through hole is formed, and a belt body including a protecting pad and a positioning structure. One end of the positioning structure is connected to the cushion body, another end of the positioning structure passes through the through hole to connect with the protecting pad, and the positioning structure biases the protecting pad away from a working position. When the belt body is not in use, the positioning structure can drive the protecting pad away from the working position by elasticity, so as to prevent the protecting pad from randomly falling on an upper surface of the cushion body, which will not affect a child's riding and can improve the riding comfort. The buckle fastening assembly has advantages of simple structure and easy disassembly, which is convenient to use by caregivers.

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.
