Set limits of joint's movement in relation to connected rigidbody

I created a humanoid character in Unity using Ragdoll Wizzard and now I am trying to set the properties of each CharacterJoint. To each joint I also added following script:

using UnityEngine;
using System.Collections;

public class MoveJoint : MonoBehaviour {

	public float minXTiltAngle = 10.0F;
	public float maxXTiltAngle = 10.0F;
	public float minYTiltAngle = 10.0F;
	public float maxYTiltAngle = 10.0F;
	public float minZTiltAngle = 10.0F;
	public float maxZTiltAngle = 10.0F;
    public float smooth = 10.0F;

	Transform jointTransform = null;
	private float initialXRotation;
	private float initialYRotation;
	private float initialZRotation;

	// Use this for initialization
	public void Start () {
		CharacterJoint characterJoint = gameObject.GetComponent( typeof(CharacterJoint) ) as CharacterJoint;

		if (characterJoint != null) {
			jointTransform = characterJoint.transform;

			initialXRotation = jointTransform.eulerAngles.x;
			initialYRotation = jointTransform.eulerAngles.y;
			initialZRotation = jointTransform.eulerAngles.z;

	// Update is called once per frame
	public void Update () {

		float tiltAroundX = 0.0F;//initialXRotation;
		float tiltAroundY = 0.0F;//initialYRotation;
		float tiltAroundZ = 0.0F;//initialZRotation;
		bool move = false;

		if (Input.GetAxis("Vertical") != 0.0F) {
			tiltAroundX = Input.GetAxis("Vertical");
			if (tiltAroundX <= 0) tiltAroundX = tiltAroundX * minXTiltAngle;
			else tiltAroundX = tiltAroundX * maxXTiltAngle;
			move = true;
		if (Input.GetKey("e")) {
			tiltAroundY = 1.0F * maxYTiltAngle;
			move = true;
 		} else if (Input.GetKey("q")) {
			tiltAroundY = -1.0F * minYTiltAngle;
			move = true;

		if (Input.GetAxis("Horizontal") != 0.0F) {
			tiltAroundZ = Input.GetAxis("Horizontal");
			if (tiltAroundZ <= 0) tiltAroundZ = tiltAroundZ * minZTiltAngle;
			else tiltAroundZ = tiltAroundZ * maxZTiltAngle;
			move = true;

		if(move) MoveWithKey(tiltAroundX, tiltAroundY, tiltAroundZ);

    void MoveWithKey(float tiltAroundX, float tiltAroundY, float tiltAroundZ){

	    Quaternion target = Quaternion.Euler(initialXRotation + tiltAroundX, 
	    initialYRotation + tiltAroundY,	initialZRotation + tiltAroundZ);

	    jointTransform.rotation = Quaternion.Slerp(transform.rotation, target, Time.deltaTime * smooth);

The script just takes input from the user and applies move to the joint (respecting initial rotation). Initial angles are set to 10, but I changed them for every joint in Unity. And here comes my question. How can I set some limits of joint’s movement in relation to rigidbody to which it is attached? Below I give screenshots, which may explain what I mean.

How should the leg look, when limits applied:

What I get now:

Hi! Probably you should use joint.swing1Limit, joint.swing2Limit, joint.lowTwistLimit and joint.highTwistLimit to limit angle rotation on each axis
