The present invention relates to new and use ful improvements in bicycle seats, and has for its primary object to provide a device of this character comprising (Cl. 155—5.20) 2 1 pneumatic cushioning means of a novel construction and arrangement. Other objects of the invention are to provide a pneumatically cushioned bicycle seat of the aforementioned character which will be com paratively simple in construction, strong, durable, ing in?ating valve I1 is provided for the pneu matic cushion l6, said valve passing downwardly through an opening provided therefor in the saddle [3. It is thought that the operation of the inven tion will be readily apparent from a considera tion of the foregoing. Brie?y, the pneumatic cushion i6 is inflated to the desired pressure. The seat 1 is secured in adjusted position on the 10 horizontal upper portion of the lever 6. As the seat 1 moves downwardly under the load thereon, compact, light in weight and which may be man ufactured at low cost. the pneumatic cushion I6 is compressed between ‘All of the foregoing and still further objects the saddle l3 and the bar Ill of the bicycle frame and advantages of the invention willbecome ap - 2. In this manner the cushion it functions as parent from a study of the following speci?ca tion, taken in connection with the accompanying 15 a shock absorber in addition to yieldingly sup porting the rider at all times. This cushioning drawings, wherein like characters of reference and shock absorbing effect may be adjusted as designate corresponding parts throughout the desired by regulating the pneumatic pressure in several views, and wherein: the cushion l6, also by moving the seat 1 for-v Figure 1 is a view in side elevation of a bicycle wardly or rearwardly on the lever 6. Of course, sea-t constructed in accordance with the present ' the lever 6 swings vertically on the post i. invention.

The angular lever 6 includes a depending forward por tion 9 Which is connected to the usual top bar It of the'bicycle frame 2 through the medium of a yieldable clamp ll. present invention will be readily understood, and although preferred embodiments of the device are as illustrated and described, it is to be under stood that further modi?cations and changes in the details of construction may be resorted to 45 which will fall within the scope of the invention As illustrated to advantage in Figures 3 and 4 as claimed. of the drawings, the yieldable clamp ll includes What is claimed is: substantially channel-shaped upper and lower 1. In a bicycle comprising a frame including saddles l2 and l3, respectively, of suitable strong, a substantially horizontal bar, a post mounted ?exible material, which are connected by links 50 on the frame and including a forwardly offset I4. The saddle l2, which is mounted on the ‘ upper end portion, an angular lever pivotally frame bar I0, is pivotally secured at l5 to the mounted at an intermediate point for vertical lower end portion 9 of the lever B. The saddle swinging movement on said upper end portion I3 is spaced below the frame bar in for receiving of the post, a seat adjustably mounted on one therebetween an inflated cushion IS.
