## Abstract

A joint assembly between a first component and a second component comprises a ball portion configured to be connected to the first component. A socket is configured to be connected to the second component or ground and comprises a socket base, a socket cover, and a spherical joint cavity within the assembled socket base and socket cover to receive the ball portion to form a spherical joint. At least one biasing member is in the joint assembly. A clamp clamps the socket base to the socket cover such that the at least one biasing member biases the socket base and the socket cover toward one another.

## Claims

### Claim 1

A joint assembly between a first component and a second component comprising:
a ball portion configured to be connected to the first component;
a socket configured to be connected to the second component or ground and comprising
a socket base,
a socket cover,
a spherical joint cavity within the assembled socket base and socket cover to receive the ball portion to form a spherical joint;
at least one biasing member in the joint assembly; and
a clamp clamping the socket base to the socket cover such that the at least one biasing member biases the socket base and the socket cover toward one another.

### Claim 2 (depends on 1)

The joint assembly according to claim 1, wherein the clamp includes a cap mounted onto the socket cover, and connected to the socket base, a translational joint being formed between the cap and the socket cover enabling biasing action of the socket cover toward the socket base.

### Claim 3 (depends on 2)

The joint assembly according to claim 2, wherein the cap includes at least one C-shaped clip contacting an annular surface of the socket base.

### Claim 4 (depends on 3)

The joint assembly according to claim 3, wherein the cap includes at least one fastener screwingly engaged to the at least one C-shaped clip.

### Claim 5 (depends on 1)

The joint assembly according to claim 1, wherein the at least one biasing member is between the clamp and the socket cover.

### Claim 6 (depends on 1)

The joint assembly according to claim 1, wherein the at least one biasing member is an elastomeric ring.

### Claim at position 7

-9. (canceled)

### Claim 10 (depends on 1)

The joint assembly according to claim 1, wherein the socket cover has a countersink opening configured for allowing connection of the first component to the ball portion, wherein the countersink opening tapers toward the ball portion.

### Claim 11 (depends on 10)

The joint assembly according to claim 10, further comprising a threaded rod received in a threaded bore in the ball portion and projecting out of the spherical joint cavity through the countersink opening.

### Claim 12 (depends on 1)

The joint assembly according to claim 1, wherein the socket base has a flange at an end away from the spherical joint cavity, and further comprising a housing enclosing the flange to form a translation joint therewith.

### Claim 13

A motion simulator comprising:
an output;
at least one linear actuator between the output and a support structure;
at least one joint assembly between the at least one linear actuator, and one of the output and the support structure, the joint assembly comprising
a ball portion connected to either the at least one linear actuator, or one of the output and the support structure;
a socket connected to either the at least one linear actuator, or one of the output and the support structure complementary to that connected to the ball portion, and comprising
a socket base,
a socket cover, and
a spherical joint cavity within the assembled socket base and socket cover to receive the ball portion to form a spherical joint;
at least one biasing member in the joint assembly; and
a clamp clamping the socket base to the socket cover such that the at least one biasing member biases the socket base and the socket cover toward one another.

### Claim 14 (depends on 13)

The motion simulator according to claim 13, wherein the clamp includes a cap mounted onto the socket cover, and connected to the socket base, a translational joint being formed between the cap and the socket cover enabling biasing action of the socket cover toward the socket base.

### Claim 15 (depends on 14)

The motion simulator according to claim 14, wherein the cap includes at least one C-shaped clip contacting an annular surface of the socket base.

### Claim 16 (depends on 15)

The motion simulator according to claim 15, wherein the cap includes at least one fastener screwingly engaged to the at least one C-shaped clip.

### Claim 17 (depends on 13)

The motion simulator according to claim 13, wherein the at least one biasing member is between the clamp and the socket cover.

### Claim 18 (depends on 13)

The motion simulator according to claim 13, wherein the at least one biasing member is an elastomeric ring.

### Claim at position 17

-21. (canceled)

### Claim 22 (depends on 13)

The motion simulator according to claim 13, wherein the socket cover has a countersink opening for connection with either the at least one linear actuator, or one of the output and the support structure, wherein the countersink opening tapers toward the ball portion.

### Claim 23 (depends on 22)

The motion simulator according to claim 22, further comprising a threaded rod received in a threaded bore in the ball portion and projecting out of the spherical joint cavity through the countersink opening.

### Claim 24 (depends on 13)

The motion simulator according to claim 13, wherein the socket base has a flange at an end away from the spherical joint cavity, and further comprising a housing enclosing the flange to form a translation joint therewith.

### Claim 25 (depends on 24)

The motion simulator according to claim 24, wherein the housing is connected to the support structure, the support structure being the floor.

### Claim at position 22

-32. (canceled)
