Systems for absorbing an impact force
View Patent ↗A system is provided that includes a mounting module configured to be coupled to a support frame and an object-support module configured to support an object. The mounting module comprises an area configured to allow at least a portion of an object supported by the object-support module to pass through the area. The system further includes a motion-guiding module coupled to the object-support module and the mounting module. The motion-guiding module is configured to guide motion of the object-support module along a first axis of the system toward the mounting module in response to a threshold force applied to the object-support module along the first axis. The motion-guiding module is configured to resist motion of the object-support module along a second axis of the system that is perpendicular to the first axis of the system.

7. The system of claim 1 , wherein the system further comprises a magnet configured to apply to the motion-guiding module a substantially constant attractive force substantially along the second axis of the system while the object-support module is at any position along the first axis of the system.
8. The system of claim 7 , wherein the motion-guiding module comprises a metal rail and the magnet is configured to apply the substantially constant attractive force to the metal rail.
9. The system of claim 7 , wherein the substantially constant attractive force resists motion of the object-support module along the first axis of the system.
10. The system of claim 1 , wherein the mounting module or the object-support module comprises a magnet configured to apply to the motion-guiding module an attractive force along the first axis of the system.
11. The system of claim 10 , wherein the attractive force decreases as the magnet loses contact with the motion-guiding module or the object-support module moves closer to the mounting module.
12. The system of claim 10 , wherein the attractive force resists motion of the object-support module along the first axis.
13. The system of claim 1 , wherein the motion-guiding module comprises a compressible section configured to compress in response to the threshold force applied to the object-support module along the first axis.
14. The system of claim 13 , wherein the object-support module is configured to move along the first axis toward the mounting module as the compressible section is compressed.
15. A vehicle comprising:
a support frame, wherein the support frame is configured to be coupled to a system comprising:
a mounting module configured to be coupled to the support frame;
an object-support module configured to support a component of the vehicle, wherein the mounting module comprises an area configured to allow at least a portion of a component supported by the object-support module to pass through the area; and
a motion-guiding module coupled to the object-support module and the mounting module, wherein the motion-guiding module is configured to guide motion of the object-support module along a first axis of the system toward the mounting module in response to a threshold force applied to the object-support module along the first axis, wherein the motion-guiding module is configured to resist motion of the object-support module along a second axis of the system that is perpendicular to the first axis of the system.
