Abstract
A car seat is constructed to be adaptable for use by children within the toddler-size range and the youth-size range. In particular, the car seat includes cam-shaped arm rests which can be rotated about an axis roughly parallel to a seat bottom, with the rotation resulting in supporting surfaces at different heights relative to the seat bottom. In addition, the car seat has a base portion which allows a seat body to be reclined relative to the base portion, and a five-point harness which is easily removed or adjusted for children of varying heights. The car seat also has a moveable or removable head support. The car seat can be adjusted for children of varying heights and weights, avoiding the costs of multiple car seats for different sized children.
Claims25
A child restraint seat comprising:
- a seat body having a back portion and a seat portion;
- and
- two arm rests movably mounted to the seat body and movable between a first position and a second position, the arm rests extending from and being substantially normal to the back portion of the seat body, each of the arm rests comprising a first supporting surface and a second supporting surface, wherein, when the arm rests are in the first position, the first supporting surfaces are positioned higher than the second supporting surfaces relative to the seat portion, and, when the arm rests are in the second position, the second supporting surfaces are positioned higher than the first supporting surfaces relative to the seat portion.
A child restraint seat comprising:
- a seat body having a back portion and a seat portion;
- and
- tow arm rests movably mounted to the seat body and movable between a first position and a second position, the arm rests extending substantially normal to the back portion of the seat body, each of the arm rests comprising a first arm supporting surface and a second arm supporting surface, wherein, when the arm rests are in the first position, the first arm supporting surfaces are positioned higher than the second arm supporting surfaces relative to the seat portion, and, when the arm rests are in the second position, the second arm supporting surfaces are positioned higher than the first arm supporting surfaces relative to the seat portion,
- wherein the biasing element comprises a compression spring.

A child restraint seat comprising:
- a seat body having a back portion and a seat portion;
- and
- two arm rests movably mounted to the seat body and movable between a first position and a second position, the arm rests extending substantially normal to the back portion of the seat body, each of the arm rests comprising a first arm supporting surface and a second arm supporting surface, wherein, when the arm rests are in the first position, the first arm supporting surfaces are positioned higher than the second arm supporting surfaces relative to the seat portion, and, when the arm rests are in the second position, the second arm supporting surfaces are positioned higher than the first arm supporting surfaces relative to the seat portion,
- wherein the arm rests do not substantially protrude laterally from the seat body in each of the first and second positions.
1 more element
A method of adjusting a child restraint seat, comprising:
- providing a seat body having a seat bottom portion and an arm rest, which extends substantially parallel to a side of the seat bottom portion, the arm rest having a first supporting surface and a second supporting surface;
- rotatably mounting the arm rest to the seat body for rotation about an axis substantially parallel to the side of the seat bottom portion;
- and
- rotating the arm rest about the axis between a first position and a second position to adjust a height thereof, wherein, when the arm rest is in the first position, the first supporting surface is positioned higher than the second supporting surface relative to the seat bottom portion, and, when the art rest is in the second position, the second supporting surface is positioned higher than the first supporting surface relative to the seat bottom portion.
1 more element
The method of adjusting a child restraint seat, comprising:
- providing a seat body having a back portion and a seat portion;
- providing an arm rest that extends from and is substantially normal to the back portion of the seat body, the arm rest having a first arm supporting surface and a second arm supporting surface;
- rotatably mounting the arm rest to the seat body for rotation about an axis substantially parallel to the side of the seat portion;
- and
- rotating the arm rest about the axis between a first position and a second position to adjust a height thereof, wherein, when the arm rest is in the first position, the first arm supporting surface is positioned higher than the second arm supporting surface relative to the seat portion, and, when the arm rest is in the second position, the second arm supporting surface is positioned higher than the first arm supporting surface relative to the seat portion.
2 more elements
A child restraint seat comprising:
- a seat body having a back portion and a seat portion;
- two arm rests, the arm rests being movably mounted to the seat body to move between a first position and a second position, the arm rests extending from and being substantially normal to the back portion of the seat body, each of the arm rests having a first arm supporting surface when moved to the first position and a second arm supporting surface when moved to the second position, the first arm supporting surface being higher than the second arm supporting surface relative to the seat portion.
A child restraint seat comprising:
- a seat body having a back portion and a seat portion;
- and
- two arm rests movably mounted to the seat body and movable between a first position and a second position, the arm rests extending substantially normal to the back portion of the seat body, the arm rests being within an outside contour of the seat body in both the first and second positions, each of the arm rests comprising a first arm supporting surface and a second arm supporting surface, wherein, when the arm rests are in the first position, the first arm supporting surfaces are positioned higher than the second arm supporting surfaces relative to the seat portion, and, when the arm rests are in the second position, the second arm supporting surfaces are positioned higher than the first arm supporting surfaces relative to the seat portion.
