Abstract
A portable booster seat for supporting a child on a chair having a retractable clamping arm that is extendable to an underside surface of a chair seat and selectively moveable to clamp the booster seat to the chair.
Claims8
A portable seat for attachment to a chair to support a child thereon, the portable seat comprising:
- a base for supporting the portable seat on a surface, the base having forward and rearward ends;
- a clamping arm moveably connected to the base at a first end by a slide block, the slide block being moveable between a first position and a second position and having a guide opening symmetrically arranged about the first axis configured to receive the first end and enable clamping arm movement bi-directionally axially along and rotationally about a first axis;
- and
- a lifting bracket connecting the slide block and the base by a linkage comprising a first link and a second link, each link being pivotally coupled at a first end to the base and at a second end to the slide block, the first link and the second link having different lengths which rotate the slide block and the clamping arm about a second axis, the second axis being orthogonal to the first axis, movement of the clamping arm about the second axis altering separation between a clamping foot disposed at a distal end of the clamping arm and the base enabling a portion of the chair to be clamped therebetween.

A portable seat for attachment to a chair to support a child thereon, the portable seat comprising:
- a base including a lower surface, the base configured for supporting the seat on a first surface and having a forward end;
- and
- a clamping mechanism connected to the base further comprising:
- a slide block connected to the base and moveable by rotation about a transverse axis between a first position and a second position, the slide block having a guide opening symmetrically arranged about a longitudinal axis, the longitudinal and transverse axes being orthogonally aligned;
- a clamping arm with a first end configured to engage the guide opening for bi-directional movement along the longitudinal axis between a retracted position, and an extended position in which a portion of the clamping arm projects forwardly from the base, and rotation about the longitudinal axis between a clamping position and a storage position, the clamping arm having a second end with a foot selectively positionable in contact with a second surface planarly opposite to the first surface and beneath the base, movement of the slide block toward the second position while the clamping arm is in the extended position moving the foot into contact with the second surface;
- and
- an actuating mechanism configured to selectively move the slide block between the first and second positions and releasably retain the slide block in the second position.
