专利汇可以提供Suspension system for vehicle mounted bed专利检索，专利查询，专利分析的服务。并且Suspension system for vehicle-mounted beds provides both fore and aft isolation and vertical isolation from pitch and vertical vibrations of the vehicle. The main frame of the suspension is mounted for vertical isolation movement relative to the frame of the vehicle by means of an air spring biased scissor-type linkage. Fore and aft isolation movement is provided by pendulously suspending the mattress support frame from pivoted links attached to the main suspension frame. The system provides especially good shock isolation for short wheel-base truck cabs of the cab over engine type where the bed is usually located at a considerable distance above the vehicle frame.，下面是Suspension system for vehicle mounted bed专利的具体信息内容。

权利要求

1. A bed construction for a moving vehicle comprising: a. a movable frame including horizontal support portions at each end thereof, b. resilient support means connected to said movable frame and to the frame of the vehicle for permitting said movable frame to move in a vertical direction relative to the frame of said vehicle; c. a mattress support member including horizontal support portions at each end thereof; and d. a pair of rigid vertical link members pivotally connecting the ends of said support portions At each end of the bed and cooperating therewith to form a parallelogram linkage for penduously supporting said mattress support member for fore and aft movement relative to the vehicle.

2. A bed construction for a moving vehicle in accordance to claim 1 wherein said resilient support means includes a gas spring.

3. A bed construction for a moving vehicle in accordance with claim 2 wherein said resilient support means further includes linkage means.

4. A bed construction for a moving vehicle in accordance with claim 3 wherein said linkage means includes a scissors linkage comprising a pair of link members pivoted to each other intermediate their ends and with one of said link members being pivoted to the vehicle frame at one of its ends and slidably mounted to the mattress support member at its other end while the other link member is pivoted to the mattress support member at one end and mounted for sliding movement relative to the vehicle frame at its other end.

5. A bed construction for a moving vehicle in accordance with claim 1 wherein said vertical link members have a length sufficient to permit said mattress support member to oscillate at a natural frequency which is less than the natural pitch frequency of a vehicle in which the bed is mounted.

6. A bed construction for a moving vehicle in accordance with claim 5 wherein said vertical link members have a length sufficient to permit said mattress support member to oscillate at a natural frequency of less than 2 Hz.

7. A bed construction for a moving vehicle in accordance with claim 5 wherein said vertical link members have a length sufficient to permit said mattress support member to oscillate at a natural frequency of approximately 1 Hz.

8. A bed construction for a moving vehicle in accordance with claim 2 wherein said movable frame comprises a sealed hollow portion which is connected to said gas spring and constitutes a reservoir therefor.

9. A bed construction for a moving vehicle in accordance with claim 8 wherein said reservoir has sufficient capacity to cause said gas spring to have a natural frequency of less than 2 Hz.

10. A bed construction for a moving vehicle in accordance with claim 8 wherein said reservoir has sufficient capacity to cause said gas spring to have a natural frequency of approximately 1 Hz.
