Adjustable and pivotable seat

Abstract

An adjustable and pivotable seat includes a base, a backrest plate and an adjusting rod. The base has a receiving portion disposed on one end of the base and a receiving space defined in the receiving portion, and an opening inclinedly defined through the receiving portion. The backrest plate is pivotally connected with the base and has a series of teeth disposed on the backrest plate and a series of slots respectively defined in between the series of teeth. The series of teeth is correspondingly and movable received in the receiving space in the base. The adjusting rod is selectively inserted into the opening and selectively engages one of the series of slots. Therefore, the backrest plate is pivotable relative to the base and an angle between the backrest plate and the base is adjustable.

What is claimed is: 
     
         1 . An adjustable and pivotable seat comprising:
 a base having a receiving portion disposed on one end of the base, the receiving portion having a receiving space defined in the receiving portion and an opening inclinedly defined through the receiving portion, extending toward a bottom of the base and communicating with the receiving space;   a backrest plate pivotally connected with the base and having multiple teeth disposed on the backrest plate and multiple slots respectively defined in between the teeth, the teeth correspondingly received in the receiving space in the base and being movable relative to the receiving portion, each slot disposed between adjacent two of the teeth and extending toward an upper part of the backrest plate which is located higher than the teeth; and   an adjusting rod selectively inserted into the opening and selectively engaging one of the slots, the adjusting rod having at least one connecting arm extending from the adjusting rod for movably connecting with the base.   
     
     
         2 . The adjustable and pivotable seat as claimed in  claim 1 , wherein the base has at least one fixing groove defined in the base for corresponding receiving the at least one connecting arm of the adjusting rod such that the adjusting rod is pivotally connected with the base. 
     
     
         3 . The adjustable and pivotable seat as claimed in  claim 2  further comprising at least one elastomer mounted on the base and each one of the at least one elastomer having two end respectively connected with the base and the adjusting rod. 
     
     
         4 . The adjustable and pivotable seat as claimed in  claim 3 , wherein the base has at least one connecting hole defined in the bottom of the base. 
     
     
         5 . The adjustable and pivotable seat as claimed in  claim 4  further comprising two sponges respectively mounted on the backrest plate and the base and two coats respectively mounted on the backrest plate and the base. 
     
     
         6 . The adjustable and pivotable seat as claimed in  claim 1  further comprising at least one elastomer mounted on the base and each one of the at least one elastomer having two end respectively connected with the base and the adjusting rod. 
     
     
         7 . The adjustable and pivotable seat as claimed in  claim 1 , wherein the base has at least one connecting hole defined in the bottom of the base. 
     
     
         8 . The adjustable and pivotable seat as claimed in  claim 2 , wherein the base has at least one connecting hole defined in the bottom of the base. 
     
     
         9 . The adjustable and pivotable seat as claimed in  claim 6 , wherein the base has at least one connecting hole defined in the bottom of the base. 
     
     
         10 . The adjustable and pivotable seat as claimed in  claim 1  further comprising two sponges respectively mounted on the backrest plate and the base and two coats respectively mounted on the backrest plate and the base. 
     
     
         11 . The adjustable and pivotable seat as claimed in  claim 2  further comprising two sponges respectively mounted on the backrest plate and the base and two coats respectively mounted on the backrest plate and the base. 
     
     
         12 . The adjustable and pivotable seat as claimed in  claim 3  further comprising two sponges respectively mounted on the backrest plate and the base and two coats respectively mounted on the backrest plate and the base. 
     
     
         13 . The adjustable and pivotable seat as claimed in  claim 6  further comprising two sponges respectively mounted on the backrest plate and the base and two coats respectively mounted on the backrest plate and the base. 
     
     
         14 . The adjustable and pivotable seat as claimed in  claim 7  further comprising two sponges respectively mounted on the backrest plate and the base and two coats respectively mounted on the backrest plate and the base. 
     
     
         15 . The adjustable and pivotable seat as claimed in  claim 8  further comprising two sponges respectively mounted on the backrest plate and the base and two coats respectively mounted on the backrest plate and the base. 
     
     
         16 . The adjustable and pivotable seat as claimed in  claim 9  further comprising two sponges respectively mounted on the backrest plate and the base and two coats respectively mounted on the backrest plate and the base.
