## Abstract

A seat assembly machine includes a plurality of grippers useful for securing a piece of trim to a seat cushion. In a disclosed example, each gripper includes a plurality of prongs that are moved between neutral, closed and released positions that each facilitate a different portion of the assembly process. In one example, each gripper includes a sleeve within which the prongs are moveable so that the prongs are manipulated between the neutral, closed and released positions. A disclosed example sleeve includes an interior channel having a contour that manipulates the prongs between the different positions based on the location of the prongs within the sleeve.

## Claims

### Claim 1

A gripper for use in a seat trim application process comprising:
a sleeve;
a plurality of prongs retractably retained within and moveable relative to the sleeve for selectively gripping a component, wherein at least one spring biases at least one end of the prongs toward one another when the prongs are in a neutral position such that the prongs are allowed to move relative to each other if the bias is overcome, wherein each of the plurality of prongs includes at least one chamfered surface adjacent the one end and facing another of the plurality of prongs, the chamfered surface being configured to facilitate insertion of the component between the prongs when the prongs are in the neutral position;
the sleeve comprises a channel having a contour that controls whether the prongs are in the neutral, a closed or a released position based on a location of the prongs relative to an end of the sleeve;
the contour includes a portion having a reduced dimension inside the sleeve near an open end of the sleeve;
the prongs include an outside surface near a more inward end of the prongs; and
the outside surface interacts with the portion of the contour to urge the at least one end of each prong away from each other to position the prongs in the released position.

### Claim 2 (depends on 1)

The gripper of claim 1, wherein the at least one spring comprises two coil springs.

### Claim 3 (depends on 1)

The gripper of claim 1, wherein each of the plurality of prongs has the one end disposed outside of the sleeve and a second end opposite the one end and disposed in the sleeve, wherein the second ends of the plurality of prongs are biased apart by the at least one spring.

### Claim 4

A gripper for use in a seat trim application process comprising:
a sleeve;
a plurality of prongs retractably retained within and moveable relative to the sleeve for selectively gripping a component, wherein at least one spring biases at least one end of the prongs toward one another when the prongs are in a neutral position such that the prongs are allowed to move relative to each other if the bias is overcome, wherein each of the plurality of prongs has the one end disposed outside of the sleeve and a second end opposite the one end and disposed in the sleeve, wherein the second ends of the plurality of prongs are biased apart by the at least one spring;
the sleeve comprises a channel having a contour that controls whether the prongs are in the neutral, a closed or a released position based on a location of the prongs relative to an end of the sleeve;
the contour includes a portion having a reduced dimension inside the sleeve near an open end of the sleeve;
the prongs include an outside surface near a more inward end of the prongs; and
the outside surface interacts with the portion of the contour to urge the at least one end of each prong away from each other to position the prongs in the released position.

### Claim 5 (depends on 4)

The gripper of claim 4, wherein a pivot member is positioned between the prongs such that biasing a second end of each of the plurality of prongs away from each other biases a first end of each of the plurality of prongs toward each other.

### Claim 6 (depends on 4)

The gripper of claim 4, wherein at least one of the prongs includes a recess disposed on the at least one of the prongs facing toward the other prong to provide a gripping surface for holding the component between the prongs.

### Claim 7 (depends on 4)

The gripper of claim 4, wherein the component is a piece of seat trim.

### Claim 8 (depends on 4)

The gripper of claim 4, wherein each of the plurality of prongs includes at least one chamfered surface adjacent the one end and facing another of the plurality of prongs, the chamfered surface being configured to facilitate insertion of the component between the prongs when the prongs are in the neutral position.

### Claim 9

A gripper for use in a seat assembly machine comprising:
a sleeve; and
a first prong and a second prong retractably retained within the sleeve for selectively gripping a component, wherein each of first prong and the second prong have a first end opposite a second end, wherein the second ends are disposed in the sleeve and biased apart by a biasing member, wherein the component is selectively gripped between the first end of the first prong and the first end of the second prong, wherein the prongs are moveable between a closed position where the prongs are prevented from movement relative to each other by the sleeve, a released position where at least the first ends of the prongs are separated from each other, and a neutral position where the first ends of the prongs are biased toward each other and allowed to move relative to each other if the bias is overcome, wherein the first ends of the prongs are a first distance from an end of the sleeve when the prongs are in the neutral position;
the first ends of the prongs are a second, smaller distance from the end of the sleeve when the prongs are in the closed position; and
the first ends of the prongs are a third distance from the end of the sleeve when the prongs are in the released position, the third distance is greater than the first distance.

### Claim 10 (depends on 9)

The gripper of claim 9, wherein
the bias is overcome by the component resulting from relative movement between the component and the prongs; and
the relative movement includes a reduction in a spacing between the component and an end of the sleeve.

### Claim 11 (depends on 9)

The gripper of claim 9, wherein the component is a piece of seat trim.

### Claim 12 (depends on 9)

The gripper of claim 9, wherein
the sleeve comprises a channel having a contour that controls whether the prongs are in the neutral, the closed or the released position based on a location of the prongs relative to an end of the sleeve;
the contour includes a portion having a reduced dimension inside the sleeve near an open end of the sleeve;
the prongs include an outside surface near a more inward end of the prongs; and
the outside surface interacts with the portion of the contour to urge the first end of each prong away from each other to position the prongs in the released position.

### Claim 13 (depends on 9)

The gripper of claim 9, wherein each of the plurality of prongs includes at least one chamfered surface adjacent the one end and facing another of the plurality of prongs, the chamfered surface being configured to facilitate insertion of the component between the prongs when the prongs are in the neutral position.
