An upper back support in a vehicle seat, with the vehicle seat having a base assembly including a seat support. The seat member is supported on the base assembly and a back frame is pivoted to the base assembly for movement. A back shell is connected to the back frame and an upper back support is coupled to the back shell. The upper back support comprises a panel having a lower portion and an upper portion, with the lower portion flexibly coupled to the back shell of the vehicle seat. A resilient member is coupled to the panel proximate the upper portion and to the back shell of the vehicle seat. An additional resilient member can be coupled to the panel proximate the upper portion and to the back shell of the vehicle seat in a spaced apart relationship to the other resilient member.

The pressure sprayer of claim 7, wherein: said pump includes a piston and a piston housing configured to receive said piston therein, and movement of said cam causes said piston to reciprocate in said piston housing. 9. The pressure sprayer of claim 8, wherein: said piston includes a piston shaft, a drive pin is attached to said piston shaft, said cam defines a cam track in which said drive pin is positioned, and movement of said cam causes said drive pin to advance through said cam track. 10. The pressure sprayer of claim 7, further comprising an axle extending between a first wheel and a second wheel of said pressure sprayer, said cam being mounted on said axle. 11. The pressure sprayer of claim 10, wherein: rotation of said first wheel and said second wheel causes movement of said axle, and movement of said axle causes movement of said cam. 12. A pressure sprayer, comprising: an accumulator for storing fluid therein under pressure; at least one wheel which rotates when said pressure sprayer is moved; and a pump which advances fluid into said accumulator in response to rotation of said at least one wheel, wherein an increased pressure is generated within said accumulator in response to fluid being advanced into said accumulator by said pump, and wherein said increased pressure within said accumulator is maintained when said at least one wheel is stationary, further comprising a hose in fluid communication with said accumulator, wherein (i) said hose has a valve mechanism coupled to one end thereof, and (ii) said valve mechanism includes a control lever. 13. A method of spraying fluid with a portable pressure sprayer having a tank, an accumulator, and a number of wheels, comprising the steps of: moving said portable pressure sprayer so as to cause said number of wheels to rotate; advancing fluid from said tank into said accumulator in response to rotation of said number of wheels; generating an increased pressure within said accumulator in response to fluid being advanced into said accumulator; maintaining said increased pressure within said accumulator after said moving step when said number of wheels are stationary; and advancing fluid from a first location within said accumulator to a second location outside of said sprayer while said number of wheels are stationary. 14. The method of claim 13, wherein: said step of advancing fluid from said first location within said accumulator to said second location outside of said sprayer includes the step of spraying fluid through a hose, said hose has a valve mechanism coupled to one end thereof, and said valve mechanism includes a control lever. 15. A method of spraying fluid with a portable pressure sprayer having a tank, an accumulator, and a number of wheels, comprising the steps of: moving said portable pressure sprayer so as to cause said number of wheels to rotate; advancing fluid from said tank into said accumulator in response to rotation of said number of wheels; generating an increased pressure within said accumulator in response to fluid being advanced into said accumulator; and maintaining said increased pressure within said accumulator after said moving step when said number of wheels are stationary, wherein said advancing step includes the step of pumping said fluid from said tank into said accumulator with a pump, and wherein (i) said pump includes a piston and a piston housing configured to receive said piston therein, and (ii) rotation of said number of wheels causes said piston to reciprocate in said piston housing. 16. A method of spraying fluid with a portable pressure sprayer having a tank, an accumulator, and a number of wheels, comprising the steps of: moving said portable pressure
