Abstract

A reclinable children'"'"'s chair or child'"'"'s chair for use on a motor vehicle seat, comprising a base frame to be placed on such vehicle seat, and a reclinable child'"'"'s seat operatively engaged with the base frame and movable generally longitudinally back and forth relative to the base frame selectively angularly between an upright rearward position and a reclined forward position, a drive mechanism, e.g. a motor and drive shaft and connecting rod linkage, mounted on the base frame and operatively connected to the reclinable seat for so moving the reclinable seat, and a control mechanism for controlling the operation of the drive mechanism e.g. a manual handle for rotating the shaft and/or a switch for operating the motor.

Claims

1. Reclinable children'"'"'s chair for use as a portable chair on a vehicle seat in a motor vehicle, comprising

a base frame adapted to be placed on such a vehicle seat, and a reclinable child'"'"'s seat operatively slidably and guidably engaged with and supported by the base frame and movable generally longitudinally back and forth relative to the base frame selectively angularly between an upright rearward position and a reclined forward position,

guide frame supports interlocked to the base frame, and a generally vertically arcuate guide frame attached to the reclinable seat for movement therewith and guidably engaged with and supported by the guide frame supports,

a rotatable transverse drive shaft mounted on the base frame and a connecting rod linkage operatively connecting the shaft to the reclinable seat for so moving the reclinable seat upon corresponding rotation of the shaft and including radial crank arm means on the shaft and connecting rod means correspondingly operatively connected at one end to the arm means and at the other end to an intermediate portion of the guide frame for transmitting rotational motion of the shaft as longitudinal motion to the reclinable seat,

limit means for limiting the movement of the reclinable seat between two opposing operative end positions corresponding to the upright and reclined positions of the reclinable seat and including generally longitudinal slot means in the guide frame provided with opposing forward and rearward slot end stop means, the shaft being arranged in the slot means for independently guidably engaging and supporting the guide frame thereat,

such that upon reclinable seat rearward movement to the upright rearward position, the forward slot end stop means will abut the shaft to limit further rearward seat movement, and in turn upon reclinable seat forward movement to the reclined forward position, the rearward slot end stop means will abut the shaft to limit further forward seat movement, and further

such that the guide frame supports and shaft on the base frame correspondingly guidably engage and support the guide frame and slot means in any position of movement of the reclinable seat, and

means for rotating the shaft.

2. Chair of claim 1 wherein the means for rotating the shaft includes a manual handle operatively connected to the shaft for manually rotating the shaft.

3. Chair of claim 1 wherein the means for rotating the shaft includes an electric reducer motor operatively connected to the shaft for rotating the shaft, and provided with switch means for operating the motor in opposite rotational directions respectively.

4. Chair of claim 3 wherein the means for rotating the shaft includes a manual handle operatively connected to the shaft for manually rotating the shaft as an alternative to the operation of the motor.

5. Reclinable children'"'"'s chair for use as a portable chair on a vehicle seat in a motor vehicle, comprising

a base frame adapted to be placed on such a vehicle seat, and a reclinable child'"'"'s seat operatively slidably and guidably engaged with and supported by the base frame and movable generally longitudinally back and forth relative to the base frame selectively angularly between an upright rearward position and a reclined forward position,

guide frame supports interlocked to the base frame, and a generally vertically arcuate guide frame attached to the reclinable seat for movement therewith and guidably engaged with and supported by the guide frame supports,

a rotatable transverse drive shaft mounted on the base frame and a connecting rod linkage operatively connecting the shaft to the reclinable seat for so moving the reclinable seat upon corresponding rotation of the shaft and including radial crank arm means on the shaft and connecting rod means correspondingly operatively connected at one end to the arm means and at the other end to an intermediate portion of the guide frame for transmitting rotational motion of the shaft as longitudinal motion to the reclinable seat,

limit means for limiting the movement of the reclinable seat between two opposing operative end positions corresponding to the upright and reclined positions of the reclinable seat and including generally longitudinal slot means in the guide frame provided with opposing forward and rearward slot end stop means, the shaft being arranged in the slot means for independently guidably engaging and supporting the guide frame thereat,

such that upon reclinable set rearward movement to the upright rearward position, the forward slot end stop means will abut the shaft to limit further rearward seat movement, and in turn upon reclinable seat forward movement to the reclined forward position, the rearward slot end stop means will abut the shaft to limit further forward seat movement, and further

such that the guide frame supports and shaft on the base frame correspondingly guidably engage and support the guide frame and slot means in any position of movement of the reclinable seat, and

means including a motor operatively connected for rotating the shaft.

6. Chair of claim 5 wherein the motor is an electric motor powered by a self-contained energy source provided on the base frame.

7. Chair of claim 5 wherein the motor is an electric motor provided with a power connection means for connection to a battery of such a vehicle for powering the motor.

8. Chair of claim 5 wherein the means for rotating the shaft further includes a manual handle operatively connected to the shaft for manually rotating the shaft as an alternative to the rotation by the motor.
