Systems, apparatus and methods implemented in algorithms, software, firmware, logic, or circuitry may be configured to process data and sensory input to determine whether an object external to an autonomous vehicle (e.g., another vehicle, a pedestrian, a bicyclist, etc.) may be a potential collision threat to the autonomous vehicle. The autonomous vehicle may include a light emitter positioned external to a surface of the autonomous vehicle and being configured to implement a visual alert by emitting light from the light emitter. Data representing a light pattern may be received by the light emitter and the light emitted by the display may be indicative of the light pattern. The light pattern may be selected to gain the attention of the object (e.g., a pedestrian, a driver of a car, a bicyclists, etc.) in order to avoid the potential collision or to alert the object to the presence of the autonomous vehicle.

Described are modular leg assemblies for passenger seats. The modular leg assemblies can include a universal first leg member, a universal second leg member, a size specific member, and a universal seat frame tube receptor. The universal first leg member may be coupled to a first seat track fitting. The universal second leg member may be coupled to a second seat track fitting. The size specific member may be coupled to the universal first leg member and to the universal second leg member. At least one of the universal second leg member or the universal seat frame tube receptor can include a set of attachment points for coupling the universal seat frame tube receptor to the universal second leg member.

A child safety seat is provided. The child safety seat includes a seat shell configured to receive and secure a child therein. The seat shell includes a top portion, a base portion, and side portions operably coupling the top portion to the base portion, and the side portions are fabric or mesh. The child safety seat further includes a support frame configured to absorb energy and that defines a seat portion and backrest portion of the child safety seat to enable the child to be secured therein.

A restraining device control system includes: a restraining device that is provided at a vehicle seat and that restrains an occupant seated in the vehicle seat; a surrounding environment detection unit that detects an environment surrounding a vehicle; and a control unit that increases a restraining force on the occupant by the restraining device in a case in which it has been predicted, from the surrounding environment of the vehicle, that vacillation of the vehicle while in an autonomous driving mode will exceed a threshold amount and that decreases the restraining force on the occupant by the restraining device in a case in which it has been predicted, from the surrounding environment of the vehicle, that the vehicle will maintain a state in which vacillation of the vehicle while in the autonomous driving mode is less than the threshold amount.

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.

A coupling structure includes a first coupling portion formed by one end portion of a first tube, and a second coupling portion formed by one end portion of a second tube, and is configured such that the first coupling portion is inserted in the second coupling portion, the first coupling portion and the second coupling portion are coupled, with the second tube being pivotable with respect to the first tube, and a gap is formed between an outer surface of the first coupling portion and an inner surface of the second coupling portion in a first state in which a fluid is not flowing through the flow path, and in a second state in which the fluid is flowing through the flow path, pressure of the fluid causes the first coupling portion to deform to expand toward an outer side of the flow path to reduce the gap.
