Abstract: A harness system with a buckle restraining function is provided and includes an upper buckle, an upper strap and a restraining device. The upper strap slidably passes through the upper buckle and includes a waist portion and a shoulder portion divided by the upper buckle. The restraining device utilizes an anti-sliding structure with high friction coefficient for engaging with the upper strap and further utilizes a stopping component for abutting against the upper buckle, which effectively restrains the upper buckle from sliding relative to the upper strap toward the waist portion for preventing a passenger's injury due to an excessive decrease of a length of the waist portion when the shoulder portion is forced during a collision or an emergency brake of a vehicle.

Abstract: A child car seat includes a seat member and a head rest device. The head rest device includes a main body and a top protection structure. The main body is connected to a top of the seat member. The top protection structure is located above the main body for protecting a top of a head of a child seated on the seat member.

Abstract: A chair includes a seat member having left and right sides formed with left and right leg-holding seats, respectively. Each of the leg-holding seats defines a leg extension bore therethrough. Each of left and right leg units has an elongated front leg extending through the leg extension bore in a respective one of the leg-holding seats. Two racks are respectively fixed to and extend along the length of the front legs. A driven shaft is journalled to a bottom face of the seat member. Two pinions are respectively fixed to opposite ends of the driven shaft, and mesh respectively with the racks. A drive unit drives rotation of the driven shaft, which in turn, results in sliding movement of the seat member along the front legs.

Abstract: A foldable stroller includes two locking devices for locking a frame body in an extended position, and a twist actuator mounted on and rotatable relative to a grip and having two cam paths disposed on an inner shell surface thereof. Two cam followers are interposed between the grip and the twist actuator, and have cam surfaces to confront and slidably engage the cam paths so as to move the cam followers along an axis when the twist actuator is rotated. Two keys are secured by the cam followers and extend radially and inwardly to be inserted into and slidable along two keyways formed in the grip. Two pulling cords respectively connect the keys with the locking devices to pull the locking devices so as to unlock the frame body when the cam followers are moved. A retaining member is disposed to prevent movement of the cam followers, and is manually operable to move radially.
