Abstract

A portable chair may include a first front leg and a second front leg connected by a front sled and a first back leg and a second back leg connected by a back sled. The first front leg and the first back leg may be pivotally connected to a sliding pivot on an armrest, where the sliding pivot moves relative to the armrest to adjust the chair from an upright position to a reclined position. The seat assembly may include a fabric member that is attached secured to a seat frame by a plurality of fabric retention members. In some examples, the portable chair may include a fabric member is releasably connected to the seat frame and back frame and also extends from a forward rail of the seat frame to a top rail of the back frame.

First claim

We claim:

1. A portable chair comprising:
a first front leg and a second front leg connected by a front sled;
a first back leg and a second back leg connected by a back sled;
a seat frame including a forward rail, a rear rail opposite the forward rail, a first seat side rail extending between the forward rail and the rear rail, and a second seat side rail extending between the forward rail and the rear rail opposite the first seat side rail,
a back frame including a top rail, a first back side rail extending downward from the top rail, and a second back side rail extending downward from the top rail opposite the first back side rail,
a fabric member releasably connected to the seat frame and the back frame, wherein the fabric member extends from the forward rail to the top rail; and
an armrest comprising an armrest body that is pivotally connected to the back frame at a rear end portion, and a control assembly connected to the armrest body, wherein the control assembly includes a sliding pivot that is pivotally attached to the first front leg and the first back leg and is also slidably engaged with the armrest, and wherein the armrest has a rear end pivotally connected to the back frame, wherein a rearward movement of the sliding pivot causes the portable chair to move from an upright position to a reclined position, wherein the sliding pivot comprises a first set of engaging teeth that engage with a second set of engaging teeth to secure the sliding pivot in a fixed location relative to the armrest body, and
wherein the portable chair has an unfolded position and a folded position.

2. The portable chair of claim 1 , wherein the control assembly further includes a side paddle that is pivotally attached to the armrest body such that when the side paddle is rotated inward, the second set of engaging teeth disengage from the first set of engaging teeth to allow the sliding pivot to move relative to the armrest body.

3. The portable chair of claim 2 , wherein the side paddle comprises an actuation portion that receives contact from a user, a receiver that defines a rotational axis and receives a pin, and an engaging portion, wherein the actuation portion and engaging portion are positioned substantially perpendicular to each other.

4. The portable chair of claim 3 , wherein the second set of engaging teeth are attached to the engaging portion of the side paddle.

5. The portable chair of claim 2 , wherein the side paddle is positioned on an outboard side of the armrest.

6. The portable chair of claim 1 , wherein the sliding pivot slides along a guide rail positioned along a bottom of the armrest body.

7. The portable chair of claim 6 , wherein the guide rail is integrally formed with the armrest body.

8. A portable chair comprising:
a first front leg and a second front leg connected by a front sled;
a first back leg and a second back leg connected by a back sled, wherein a first back leg extension is positioned between the first back leg and the back sled and a second back leg extension is positioned between the second back leg and the back sled, wherein the first back leg extension extends in a different direction than the first back leg;
a seat frame including a forward rail, a rear rail opposite the forward rail, a first seat side rail extending between the forward rail and the rear rail, and a second seat side rail extending between the forward rail and the rear rail opposite the first seat side rail,
a back frame including a top rail, a first back side rail extending downward from the top rail, and a second back side rail extending downward from the top rail opposite the first back side rail,
a fabric member releasably connected to the seat frame and the back frame, wherein the fabric member extends from the forward rail to the top rail; and
an armrest comprising an armrest body that is pivotally connected to the back frame at a rear end portion, and a control assembly connected to the armrest body, wherein the control assembly includes a sliding pivot that is pivotally attached to the first front leg and the first back leg and is also slidably engaged with the armrest, and wherein the armrest has a rear end pivotally connected to the back frame, wherein a rearward movement of the sliding pivot causes the portable chair to move from an upright position to a reclined position, wherein the sliding pivot comprises a first set of engaging teeth that engage with a second set of engaging teeth to secure the sliding pivot in a fixed location relative to the armrest body, and
wherein the portable chair has an unfolded position and a folded position.

9. The portable chair of claim 8 , wherein the first back leg extension forms an obtuse angle with the first back leg.

10. A portable chair comprising:
a first front leg and a second front leg connected by a front sled;
a first back leg and a second back leg connected by a back sled;
a seat frame including a forward rail, a rear rail opposite the forward rail, a first seat side rail extending between the forward rail and the rear rail, and a second seat side rail extending between the forward rail and the rear rail opposite the first seat side rail,
a back frame including a top rail, a first back side rail extending downward from the top rail, and a second back side rail extending downward from the top rail opposite the first back side rail,
a fabric member releasably connected to the seat frame and the back frame, wherein the fabric member extends from the forward rail to the top rail, wherein the fabric member includes a plurality of side portions, wherein each side portion of the plurality of side portions is secured to one of the first side seat rail, the second side seat rail, the first back side rail, and the second back side rail using a plurality of fabric retention members, and
an armrest comprising an armrest body that is pivotally connected to the back frame at a rear end portion, and a control assembly connected to the armrest body, wherein the control assembly includes a sliding pivot that is pivotally attached to the first front leg and the first back leg and is also slidably engaged with the armrest, and wherein the armrest has a rear end pivotally connected to the back frame, wherein a rearward movement of the sliding pivot causes the portable chair to move from an upright position to a reclined position, and
wherein the portable chair has an unfolded position and a folded position.

11. The portable chair of claim 10 , wherein the plurality of fabric retention members comprise a plurality of complementary mechanical fasteners, wherein each complementary mechanical fastener includes a first mechanical element and a second mechanical element that connect together to form a releasable connection.

12. The portable chair of claim 11 , wherein the first side seat rail includes a first set of first mechanical elements and the second side seat rail includes a second set of first mechanical elements that face each other.

13. A portable chair comprising:
a first front leg and a second front leg connected by a front sled;
a first back leg and a second back leg connected by a back sled;
a seat frame including a forward rail, a rear rail opposite the forward rail, a first seat side rail extending between the forward rail and the rear rail, and a second seat side rail extending between the forward rail and the rear rail opposite the first seat side rail,
a back frame including a top rail, a first back side rail extending downward from the top rail, and a second back side rail extending downward from the top rail opposite the first back side rail,
a fabric member releasably connected to the seat fra
